if you brown the meat first -roasts and whatnot...cooking in a crock pot isn't too shabby.
pulled pork- 2 lb pork shoulder, season with whatever you prefer; let sit a few ticks, brown seasoned meat in a lightly oiled pan (yes this will require some work-holding the roast there in different positions while the side touching the pan browns), put in crock pot on a bed of sliced onions, add 1 can of root beer. Set on low for 4-6 hrs, remove from crock pot, shred, return to crock pot with a little bit of the leftover cooking liquid and your favorite BBQ sauce.
