A close friend made this Mexican-Italian bake for me almost 20 years ago, and I've prepared it regularly ever since. It comes together in a snap because it relies largely on convenient ingredients I keep on hand. We like it with a loaf of crusty bread. —Rose Turner Minnick, Christiansburg, Virginia
