I made these one night when I was hungry, but didn't feel like eating meat at all. So I looked for some ingredients and figured I would fool around w/ what I had and this is what I made. Very filling! I topped mine w/ light sour cream.
Heat oil in lg saucepan, over medium heat. Add onion to pot. Cook until soft. Stir in beans and corn. Add brown sugar, salsa and red pepper flakes.
Cook 3 mins, or until heated through. Melt 2 tsp butter in lg skillet, over medium heat. Place 1 tortilla in skillet. Sprinkle evenly w/ cheese, top w/ some of the bean mix. Place another tortilla on top of bean mix in skillet. Cook until golden.
Flip tortilla over and cook other side until golden. Place cooked tortilla on a plate. Melt more butter and repeat w/ remaining ingredients. Serve tortillas w/ extra salsa and sour cream.
