Mexican migas
In different areas of Mexico, migas is a traditional breakfast dish consisting of corn tortilla strips fried on a pan or griddle until almost crispy, to which eggs are then added to create a scrambled egg/fried tortilla mixture. This preparation makes use of hardened corn tortillas left over from previous meals. Chilaquiles is a similar meal that substitutes salsa for eggs during cooking. Both are hearty, inexpensive working-class breakfast meals.

Tex-Mex migas
There is also a Tex-Mex variation of Mexican migas. This includes additional ingredients, such as diced onions, sliced chile peppers, diced fresh tomatoes, or cheese, as well as various spices and condiments (e.g., salsa or pico de gallo).
 
Migas is typically served with refried beans, and corn or flour tortillas may be used to enfold all of the ingredients into tacos. In some areas, it may have been traditionally eaten during Lent.
