Preheat oven to 375 degrees F and line 2 large baking sheets with parchment paper. Set aside.
In a large mixing bowl, add cooked chicken, bell peppers, cumin, salt and pepper. Stir well to combine.
On a half of tortilla sprinkle 1/4 cup of cheese, spread heaping 1 cup of filling and sprinkle with 1/4 cup of cheese. Fold the other half of tortilla on top, pressing on it and making a half moon shape. Place on a baking sheet.
Repeat and make 4 more quesadillas. You can make 5 or more quesadillas by using less filling and cheese in each one. It's up to you!
Bake for 20 minutes or until the edges and bottom are golden and tops are slightly browned, and cheese is bubbling. Remove from the oven, let rest for 1-2 minutes and using sharp knife, cut each quesadilla in 3 pie-shaped wedges.
Serve warm with salsa, guacamole and sour cream or Greek yogurt.
Notes
Store: Refrigerate leftovers for up to 2 days.
Freeze: For each quesadilla, assemble and then wrap in plastic wrap as tightly as possible. Lay flat in a gallon size Ziploc bag, seal and freeze for up to 3 months. Bake from frozen at 375 degrees F for 25-30 minutes.
