Reheat the leftover chicken and vegetable fajita filling until warm but not hot (preferably in a microwave for ease of speed).
Once the fajita filling is warm, heat a frying pan on medium heat.
Add a teaspoon of oil to the pan. Then add 1 tortilla. Top with a handful of shredded cheese, diced chicken, fajita veggies, and more cheese. Add another flour tortilla on top. Cook for 2-3 minutes until the bottom is brown, then carefully flip the quesadilla over and cook for an additional 2-3 minutes.
Remove from frying pan, cut and serve. Repeat until all the quesadillas have been cooked. Serve with sour cream.
