2-3 cups filling: leftover cooked vegetables, cooked meat, crumbled tofu, cooked beans, fresh or frozen corn, cooked rice or grains, or any other leftovers.
Prepare the filling: Pick a few of the suggested filling ingredients above, enough to make 2-3 cups of total filling. If combining leftovers, warm them briefly in the microwave or in a skillet over medium heat. If using raw ingredients, cook before making quesadillas. Transfer the filling to a bowl and cover to keep warm.
