Servings 4 servings


  • 1 tablespoon avocado oil
  • 1 tablespoon fajita seasoning see recipe below
  • 1 small yellow onion sliced
  • 1 small zucchini sliced
  • 1/2 cup fresh or frozen corn kernels I like Trader Joe's fire-roasted corn
  • 1 15-ounce can black beans, drained and rinsed
  • 4 medium whole grain tortillas
  • 1 cup shredded Mexican blend or pepper jack cheese
  • Chopped cilantro and lettuce sliced green onions, diced tomatoes, avocado, crema, pickled jalapeños, salsa, and/or any other toppings you'd like

For the fajita seasoning

  • 2 tablespoons chili powder
  • 1 tablespoon salt
  • 1 tablespoon sugar
  • 1 tablespoon smoked paprika
  • 2 1/2 teaspoon crushed vegetable bouillon cube
  • 2 teaspoons dried oregano
  • 1 1/2 teaspoon onion powder
  • 1 1/2 teaspoon ground cumin
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon crushed red pepper flakes


  • Preheat broiler. Spray a large baking sheet with oil or cooking spray.
  • Heat the avocado oil in a large skillet over medium-high heat. Stir in the fajita seasoning, then add the sliced onion. Cook for about 5 minutes, or until softened, then stir in the zucchini and corn. Cook until zucchini is softened, about 3 minutes. Fold in the beans and remove from heat.
  • Arrange the tortillas on the prepared baking sheet. Broil until crisp, about 2 minutes - broilers can vary wildly, so keep a close eye on the tortillas to make sure they don't burn.
  • Divide the cheese and fajita vegetables onto each tortilla. Return to the oven and broil until the cheese has melted, about 2 minutes.
  • Transfer the tostadas to plates and add toppings.
  • To make the fajita seasoning: Combine all of the ingredients in a small jar, cover, and shake to combine.


You can substitute store-bought fajita seasoning for homemade if you prefer.
