Heat a pot or a large skillet over medium heat. Add the oil, onion, bell pepper, poblano pepper, corn, jalapeño and garlic. Saute until cooked through about 5 minutes.
Assemble your quesadilla and get ready to cook it! First, take slather half of each tortilla with the refried black bean mixture (about 1/4 cup per tortilla).
Fold tortillas in half. Spray a large nonstick skillet or a large griddle with olive oil cooking spray, and let the quesadilla cook until it’s brown and crispy.
