My husband found this cut of beef called teclas de lomo the other day. We used to buy it at a specialty shop years ago when we lived in another area. I can't find a translation, but they look like this:

Then we heated up some blue corn tortillas on the grill and filled them with the meat and salsa. They were really good.
