Build a healthy vegetarian main dish with this towering hot tortilla pie.
Preheat oven to 450 degrees F. Lightly coat a 9-inch pie plate with cooking spray.
Mash the beans; stir in jalapeno peppers, if desired. In a skillet cook and stir the beans over medium heat for 2 minutes; set aside.
Spoon 1/4 cup of the salsa into bottom of the pie plate. Layer in order, 1 tortilla, half of the warm beans, another tortilla, the corn, half of the cheese, 1/4 cup more salsa, the third tortilla, remaining beans, remaining tortilla, and salsa. Cover with foil. Bake 12 minutes. (Or, cover with microwave-safe plastic wrap; micro-cook on high power for 4 minutes, giving a half-turn once.) Sprinkle with remaining cheese. Bake, uncovered, 3 minutes more (or micro-cook 30 seconds more). Sprinkle with avocado and cilantro. Makes 4 main-dish servings.
