Preheat the oven to 350°F. Lightly grease a 9- x 13-inch baking pan.

Prepare sauce in blender by blending tomatoes, peppers, chili powder, onion, garlic, chili pepper and salt until smooth. Pour 1 cup sauce in the bottom of the pan.

Place large tablespoons of corn, then black beans, then sauce, then cheese into the center of a tortilla. Roll up and place seam-side down in a 9x13 baking dish. Repeat until all tortillas are filled.

Top with remaining sauce and sprinkle with remaining cheese. Bake, uncovered, for 20 minutes or until the sauce is bubbly and the cheese is melted. Cool slightly before cutting and serving.
