What is a quesadilla? A quesadilla is a Mexican dish that uses tortillas (corn or flour) with a filling, folded in half, and cooked until the tortilla is crispy (kind of like a flat taco).

How to make quesadillas?

  • CHICKEN– Cut the chicken into thin strands. TIP: You can use chicken breast or chicken thighs.
  • VEGETABLES– Cut peppers and onion into strands (you want to keep them the same size for even cooking).
  • COOK CHICKEN– Add oil to a skillet, once hot, sauce chicken and season with homemade seasoning. Remove from the skillet and cover to keep warm. TIP: You can use store-bought seasoning or just season with your favorite seasoning.
  • COOK VEGETABLES– In the same skillet, saute the vegetables until tender. Add the chicken back and mix everything.
  • ASSEMBLE– Add chicken and veggie filling to one half of the quesadilla. Generously top with cheese. Repeat with the second quesadilla.
  • COOK QUESADILLAS– Add both quesadillas to the skillet. Cook until the tortilla is crispy, flip, and cook until the other side is crispy and cheese melts (if you need to, turn the heat down and cook until cheese melts).

We use chicken for these fajitas, however, you can use shrimp or steak as a substitute with wonderful results.
