  • 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


  1. Preheat broiler. Spray a large baking sheet with oil or cooking spray.
  2. 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.
  3. 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.
  4. Divide the cheese and fajita vegetables onto each tortilla. Return to the oven and broil until the cheese has melted, about 2 minutes.
  5. Transfer the tostadas to plates and add toppings.
  6. To make the fajita seasoning: Combine all of the ingredients in a small jar, cover, and shake to combine.
