1Combine tomatoes, 1/4 cup chopped cilantro, and lime juice in bowl and set aside (I have used fire-roasted tomatoes with some oregano and they have worked, as well).
2Spray 8x8" baking dish with nonstick spray and preheat oven to 375 degrees.
3Arrange 1/4th of the torn tortillas in the bottom of the dish;spoon 1/4h of the tomato mixture over the tortillas; top with 1/4th of the beans, 1/4 of the corn and 1/4th of the cheese. Repeat 3 more times.
4Bake 25 minutes or until cheese is melted and sauce is bubbly. Sprinkle with remaining cilantro. Let stand 10 minutes before serving.
