Feta cheese, avocado, and red peppers combine with black beans and salsa for a flavorful meatless quesadilla that's great for lunch or dinner.
Heat oven to 400°F. In a medium bowl, mash together black beans and salsa. Divide among 4 tortillas. Top with red pepper, avocado, and feta. Place remaining tortillas on top and sandwich together.
Place quesadillas on a large greased baking pan. Spray quesadillas with vegetable cooking spray. Bake 10 minutes. Cut into quarters and serve with extra salsa, if desired.
