Here's my recipe for some Yummy Crock Pot Baked Beans. I use a 6.5 quart crock pot. You can adjust the ingredients to suit your family's tastes.
3 28 oz. cans of baked beans (including liquid)
½ cup BBQ sauce
½ onion diced
1 bell pepper diced
2 cayenne peppers diced
1+ Tbs. spicy mustard
1 Tbs. Worcestershire sauce
Spray large (6-7 quart) crock pot with non-stick spray. Add all ingredients and stir to mix well. Cook in crock pot on low for 3-4 hours.
For a smaller 4-5 quart crock pot use 2 cans of beans, and adjust other ingredients to your liking.
