Beans aren't a part of chilaquiles, they are generally a side dish,
Chilaquiles are quartered stale corn tortillas, lightly fried and then
cooked or covered n a red sauce and topped with an egg ( that is the
bare bones version for breakfast) Obviously cooks everywhere add
their own touch. Have it for breakfast, make it into a casserole. Add
chicken, or whatever protein you like. At least that is what the
Mexicans in my city do.
