I do a boneless pork roast in the crockpot with an envelope of Lipton dry onion soup, 1 can of jellied cranberries chopped over the top of the roast then put the lid on the pot and turn to high for 4 hours or medium for 6 hours for about a 2 pound roast. The juice is yummy served over rice or I'll do mashed potatoes and gravy (NOT using the cranberry drippings in the gravy). Leftovers make wonderful sandwiches, or warmed up with a salad or cole slaw and nice crusty Artisan bread. Yum!!
It should be noted that each crockpot heats differently. The time for the roast is for my crockpot. You might want to check you roast at the 4 hour mark so you don't over or under cook the meat.
