Chilaquiles de Queso al HornoSimple casseroles made with leftover corn tortillas are popular in Mexico. Corn tortillas are fried, combined with whatever is handy, then baked. Chilaquiles de queso can be served for a light meal, or even for breakfast with ham, sausage, or eggs. If tortillas are fresh, spread out on a flat surface about 30 minutes to dry a bit before using.
