Spicy, smokey, flavorful fajita chicken with caramelized bell peppers and onions. Add some fresh avocado, sour-cream, lime and cilantro and don’t forget the cheese. Place this mouth-watering mixture in a flour tortilla and pan sear just until the outside is crisp and the inside is gooey and melted. Who can say no to these quesadillas?! 
Chicken Avocado QuesadillasI’ve been making this exact quesadilla recipe for years and we just can ‘t get enough of it. This recipe is a jazzed version of my famous chicken and avocado burritos. Don’t let the bold flavors intimated you though because these quesadillas are pretty easy to make and can be made ahead of time. They can also be frozen for meal prep. After cooking them, they can be stored in ziplock bags in the freezer or fridge.

To make the mixture, cook chicken breasts, bell peppers, onion, and tomatoes in fajita spices. Then to make the quesadillas, fill a tortilla with cheese, sour-cream, avocado and some of the chicken mixture, fold and pan sear until crispy. Enjoy these warm quesadillas with guacamole, salsa, or sour-cream!

Cook for 2 minutes or until tomatoes are softened. Dice the cooked chicken and return to the pan. Stir until mixture if fully combined.

  • To assemble:Add 1 teaspoon oil to a hot pan. Lay 2 tortillas on pan. Spread 1 teaspoon sour-cream over one side of each tortilla, top with cheese, avocado, chicken mixture and squeeze of lime and sprinkle of minced cilantro. Fold the tortillas over to cover the fillings and form a half-moon shape. Cook until the tortillas are crisp and golden and the cheese has melted, about 2-3 minutes on each side. Repeat to make 2 more quesadillas.

  • Cut the quesadillas into wedges. Serve with lime wedges, sour-cream, salsa or guacamole and enjoy immediately.


To make your own seasoning. The store-bought packets work great in this dish because of the smokey flavors. To make your own fajita seasoning for this dish, combine 1 teaspoons chili powder, 1 teaspoon smoked teaspoon paprika, 1 teaspoon salt, 1 teaspoon cumin, 1/2 teaspoon garlic powder, and half a teaspoon black pepper.
