I made "beef barbacoa" tacos from leftover pot roast

I hate wasting food but being single I usually have a hard time using up a larger dish like pot roast before getting sick of it. I was looking in the pantry trying to think of some way to re-purpose the last bit of pot roast meat and saw the tortillas and a light went off. Simmered the meat in a little water with cumin, paprika, oregano, garlic powder and added a couple heaping spoons of fresh salsa. Ran down and grabbed some cilantro, onion, limes and radishes for a few bucks and was pretty happy with the change of pace.
