Recipe for Fresh and Nutritious Soy Ceviche Tostadas

Hello! We are going to prepare an incredibly fresh option that surprises everyone with its texture and flavor, ideal for those looking to reduce meat consumption without sacrificing taste. These tostadas are crispy, tangy, and full of vegetables, perfect for sharing with family any day of the week.

If you love seafood flavors but want to try something plant-based, this preparation will remind you a lot of traditional ceviche recipes, but also taking care of your wallet and health. The key here is how we treat the soy so that it absorbs all the flavor of the lemon and spices.

Preparation time

Organize your time in the kitchen to have everything ready without rushing:

  • Preparation: 25 minutes
  • Cooking: 20 minutes
  • Total: 45 minutes
  • Servings: 4 to 6 people
  • Difficulty: Easy

Ingredients

For the soy base

  • 2 cups textured soy (dry)
  • Enough water to cover and boil
  • 1/4 white onion (for boiling)
  • 1 peeled garlic clove
  • 2 dried bay leaves

For the marinade and ceviche

  • 1/2 cucumber, peeled and deseeded (for blending)
  • 2 tablespoons seasoning sauce (Maggi type)
  • 2 tablespoons soy sauce
  • 1/2 teaspoon onion powder salt
  • 1/4 teaspoon ground black pepper
  • 1 teaspoon dried chili flakes
  • 1/2 red onion finely sliced
  • 2 large tomatoes, deseeded and diced
  • 4 limes (freshly squeezed juice)
  • 1/2 additional cucumber cut into small cubes (optional for more texture)
  • 1 serrano chili finely chopped (optional if you like fresh spice)

To assemble

  • 1 ripe avocado
  • Baked or fried corn tostadas
  • Sprigs of disinfected fresh cilantro

If you cannot find textured soy in your usual supermarket, you can look for it in bulk or health food stores; if not possible, a functional alternative is to use blanched grated cauliflower, although the texture will change a bit.

Utensils we will use

  • Medium pot for boiling water
  • Large colander or sieve
  • Blender
  • Stable cutting board
  • Sharp chef's knife
  • Large bowl or glass mixing bowl
  • Lime squeezer
  • Large spoon for stirring

Preparation

  1. Hydration and cooking of the soy

    Boil water with aromatics. Place the pot over high heat with enough water, the piece of white onion, the garlic clove, and the bay leaves. Wait for it to come to a vigorous boil.

  2. Cook the textured soy. Add the dry soy to the boiling water. Reduce heat to medium and cook for approximately 15 to 20 minutes, or until you notice it is completely soft to the touch and has doubled in size.

  3. Drain and cool. Pour the contents of the pot into the colander. Remove the onion, garlic, and bay leaf. Rinse the soy under cold running water until it loses temperature. This step is vital to stop the cooking.

  4. Squeeze out excess water. With the help of the colander or by pressing with your (clean) hands, remove as much liquid as possible from the soy. It should be moist but not soaked so it can absorb the sauce.

  5. Preparation of the marinade sauce

    Blend the liquid base. In the blender cup, place the half peeled cucumber, the seasoning juice, the soy sauce, the salt with onion powder, the black pepper, and the lime juice. Process until you get a salsa verde liquid and homogeneous.

  6. Mix and rest

    Integrate the solid ingredients. In the large bowl, place the already squeezed soy. Add the sliced red onion, the tomato cubes, the chopped cucumber (if you decided to add extra for texture), and the chili flakes.

  7. Incorporate the marinade. Pour the blended mixture over the soy and vegetables. Stir with a spoon to ensure everything is evenly coated. It's similar to how we would prepare a red aguachile but using this green and vegetable base.

  8. Rest to concentrate flavors. Cover the bowl and refrigerate for at least 15 to 20 minutes. The cold helps the soy firm up and the lemon flavor «cure» the onion, softening its potency.

To finish and serve

Once the resting time has passed, remove the ceviche from the refrigerator and taste for salt; adjust if necessary. Cut the avocado into cubes or slices just before serving to prevent it from oxidizing. Take a crispy tostada, serve a generous portion of the soy ceviche on top, draining a little of the juice so as not to moisten the base too quickly, and top with avocado and fresh cilantro leaves. You can accompany it with a little extra hot sauce if you wish.

5 keys to make it perfect

The success of a vegetable dish that imitates seafood lies in the texture and intensity of the seasoning. Here are my secrets so no one notices the difference.

1. Washing is non-negotiable. Many people complain about a «cardboard» taste in soy. This is eliminated by rinsing it very well after boiling. Don't be afraid to wash it two or three times under the tap and squeeze it hard; soy is resistant.

2. The correct acidity. Lemon does not cook soy as it would fish in a traditional ceviche, but it is the vehicle for flavor. Use small, green limes (Colima type) which tend to be more acidic and aromatic than large yellow ones.

3. Uniform cuts. To make every bite enjoyable, try to make the tomato and cucumber cubes the size of a small pearl (brunoise). If you leave very large pieces, the integration with the soy will be lost.

4. Intense cold. This dish should be eaten very cold. If you serve it lukewarm, it loses its fresh charm. Keep the mixture in the refrigerator until the last second before assembling the tostadas.

5. The extra crunchy touch. If you want to elevate the level, you can add a little raw chopped jicama to the final mixture. It provides a sweet crunch that wonderfully contrasts with the saltiness of the soy sauce, something we also do in the jicama tostadas.


When is it ideal to enjoy it?

This dish screams summer and sunny days. It is the undisputed star of the Lenten or Holy Week season, when we seek to avoid red meats, but honestly it's a lifesaver for any quick weekday lunch.

Being a light and digestive dish, it works very well as an appetizer before a main course or as a light dinner if you control the amount of tostadas. It is also excellent for gatherings where you have vegan or vegetarian guests; it is a fresh appetizer that brings everyone together at the table without complications.
