Tortilla Lasagna

Directions

1. In a large skillet, cook beef over medium heat until no longer pink; drain. Stir in the water, taco seasoning, garlic powder and cayenne. Bring to a boil. Reduce heat; simmer, uncovered, for 10 minutes.

4. Bake, uncovered, at 375° for 40 minutes. Sprinkle with remaining cheese mixture. Bake 10 minutes longer or until cheese is melted. Let stand for 10 minutes before cutting.
