Southwestern Pulled Pork

I got this recipe from Taste of Home. It's another one we all like. I'll have to add a picture later.

Southwestern Pulled Pork
adapted from tasteofhome

3 lb-ish pork roast
1 c. barbecue sauce (make sure it's a good one. I suggest trying the one Danielle posted - it's fantastic!)
1 can (8 oz) tomato sauce
2 cans chopped green chiles
1 sweet onion, thinly sliced
2 Tbl chili powder
1 tsp cumin
1/2 tsp oregano

Cook the roast in 1-2 cups of beef broth, with some S&P and garlic powder in a crock pot on low for 6-8 hrs (or you can just cook the roast in all of the ingredients, if you don't care about draining off the drippings). Remove pork and shred. Remove juices from crock pot and add the rest of ingredients. Add shredded pork and continue to cook for about 2 more hours. Serve on tortillas with lettuce, cheese, tomatoes, sour cream, etc.
