Vegetarian Black Beans Quesadillas

0 Heat oil in a large nonstick skillet over medium-high heat. Add onion, oregano, salt, pepper, and poblano, and sauté 5 minutes or until onion is tender.
1 Add mango, avocado and beans; cook a few minutes on low heat until thoroughly heated.
2 Take one tortilla, and arrange about 3/4 cup of the bean/veggie mixture on half of the tortilla. Sprinkle 2 Tbsp cheese over the bean mixture.
3 Fold the tortilla in half and warm a large skillet on the stove top. Spray the skillet with olive oil cooking spray. 
4 To Cook On The Stovetop: Spray a large skillet with cooking spray and heat over medium heat. Place the quesadilla in the pan, and cook it on either side until it is lightly browned (a few minutes on each side). This method is super easy, and perfect if you're just making a few quesadillas to order.
5 To Cook in the Oven: Preheat your broiler. Assemble all the quesadillas, place them on a large baking sheet coated with cooking spray. Spray the tops of the quesadillas with cooking spray, and place them under the broiler (in most kitchens this is the top rack of your oven). Broil for 5 minutes or until cheese melts and the tops are nice and golden brown.
6 Cut your quesadillas into triangles, serve warm with green onions, avocado, salsa or your favorite toppings!
