Black Bean and Corn Quesadilla

Warm oil in a large skillet over medium heat.

Add onion and cook until softened, about 2 minutes.

Stir in black beans, corn, tomato sauce, and red pepper flakes.

Mix well and cook until heated through, about 3 minutes. Transfer to a dish.

Wipe the skillet clean. Lay a tortilla in the skillet.

Sprinkle cheese evenly over the tortilla.

Top with about 1/4 of the bean mixture and cover with another tortilla.

Cook until the bottom is golden, then flip and cook the other side until golden.

Transfer quesadilla to a plate.

Repeat with remaining tortillas and filling.

Slice and serve warm.
