Step 1: Prepare the Chicken
Season the chicken breasts with Kosher salt and freshly ground black pepper. Heat 1 teaspoon of olive oil in a skillet over medium heat. Add the chicken breasts and cook for about 6-7 minutes on each side, or until cooked through and no longer pink in the center. Remove from the skillet and let them rest.
Step 2: Sauté the Vegetables
In the same skillet, add the remaining teaspoon of olive oil. Once heated, add the finely chopped onion and bell peppers. Sauté for about 3-4 minutes until the vegetables are soft. Add the chopped garlic and cook for another minute. Then, stir in the diced tomatoes and fajita seasoning. Mix well and cook for an additional 2 minutes.
Step 3: Shred the Chicken
While the vegetables are cooking, shred the cooked chicken using two forks. Once the vegetables are done, add the shredded chicken to the skillet and mix everything together. Allow the mixture to heat through for a few minutes.
Step 4: Assemble the Quesadillas
Lay one tortilla flat on a clean surface. Spread a quarter of the chicken mixture on one half of the tortilla. Top with a few slices of avocado, a spoonful of sour cream, and a sprinkle of cheese. Fold the tortilla in half to create a semi-circle.
Step 5: Cook the Quesadillas
Heat the skillet over medium heat again. Place the folded quesadilla in the skillet and cook for about 3-4 minutes on one side until golden brown and crispy. Carefully flip the quesadilla and cook for an additional 3-4 minutes on the other side. Repeat the process for the remaining tortillas.
Step 6: Serve and Enjoy
Once cooked, remove the quesadillas from the skillet and let them cool for a minute before slicing them into wedges. Serve with fresh lime juice and minced cilantro, if desired. Enjoy your Chicken Avocado Quesadillas warm!
