Step 1
Heat the olive oil in a large non-stick skillet over medium-high heat. Once hot, add the onion and peppers. Cook for 6-8 minutes until softened. They should still have some texture.
Step 2
Stir in the cooked turkey, black beans, and taco seasoning. Stir together and remove from heat. If using ground turkey, add the ground turkey to the pan and cook for 6-8 minutes until cooked through. Then add the taco seasoning and black beans.
Step 3
Add this mixture to a bowl and use a paper towel to clean out the pan. Heat the skillet over medium-high heat. Place the tortilla in the skillet and sprinkle one-half with about 3 tbsp of cheese. Add about 2/3 cup of the turkey filling. Top with another 3 tbsp of cheese. Fold the tortilla over and cook on one side until the cheese is melting and the tortilla begins to brown.
Step 4
Flip over and cook on the other side for 2-3 minutes more until the tortilla browns and cheese is fully melted. Repeat with remaining quesadillas.
