Originally from Betty Crocker. I've simplified it a bit. This is awesome in fajitas or burritos!!
1 boneless pork loin roast, (1½ to 2½ pounds)
1 medium onion, thinly sliced
2 C barbecue sauce
¾ C salsa
1 T chili powder
1 tsp ground cumin
½ tsp salt
Shred pork, using 2 forks, and mix well with sauce. Stir in salt. Increase heat setting to High. Cover and cook 30 minutes more.
Serve with tortillas, guacamole, shredded cheese, etc.
