Carnitas are basically just Pork Roast tacos. I don't claim that this is authentic, but its still tasty.
Leftover Pork Roast or BBQ
hot sauce to taste
Warm the pork and shred it, putting it on top of two warmed corn tortillas. The pork really likes to bust through tortilla walls. Top with cilantro and onions and hot sauce. It is an easy leftovers meal.
