To make these easy veggie quesadillas, combine the black beans, tomatoes/green chiles, corn, cilantro, and taco seasoning in a large bowl. Toss until all ingredients are combined and season with salt/pepper to taste.

Heat a large skillet or stovetop grill to medium heat and add a couple of tablespoons of oil. Place the tortilla in the skillet or on the grill, and fill half of the tortilla with about 2 tablespoons of shredded cheese, and a serving of the veggie mixture.

Fold and cook for about 2 minutes on each side or until the surface is slightly crispy and brown. Cut into wedges and serve.
