I hesitate to even call this a steak taco recipe because it’s SO simple. But readers are always asking me for tips on using up leftovers, and this is one of my favorite ways. We don’t usually have leftover steak since Eric and I typically split a steak between to make it more affordable. But when I go to my dad’s for a barbecue we almost always get sent home with a bag of steak to play with. I love using the leftovers in tacos because the result is so fresh that no one would guess your meat is a few days old.
