Barbecue Beef: 2 lbs beef stew meat (I buy the cheapest cut of meat since it will be really tender when it's done cooking!) 1 cup ketchup 1/4 cup water 1 package onion soup mix or 3 Tbsp 1/4 cup brown sugar 1 1/2 tsp prepared mustard 1/4 cup vinegar 2 cups celery, diced Place beef in the bottom of the crock pot. Mix the remaining ingredients in a bowl. Pour over the beef. Cook on low for 6 - 8 hours or high for 4 - 5 hours. Serve over rice or mashed potatoes. Of course, I'll add more veggies on the side or a salad.
