In a bowl, combine beans, corn, cheese, chili powder, salt, and cilantro.
Spread the filling onto one half of each tortilla, fold, and press the edges together.
Wrap each quesadilla in foil, refrigerate promptly until cold, and pack at 40°F (4°C) or below in an insulated cooler with ice or frozen gel packs. Cook the same day.
While at camp, heat a tablespoon of oil in a skillet over medium heat on your single burner.
Take one quesadilla out of the package. Then, cook it for about 2-3 minutes on each side. Cook until the cheese has melted and the tortilla has browned.
Repeat the process, and for the ones completed cover them using foil to keep them warm.
