Sweet and Sour Beans

Another recipe from Denise:
8 bacon strips, diced (can be made without)
2 medium onions, chopped
1 cup packed brown sugar
1/2 cup cider vinegar
1 tsp salt
1 tsp ground mustard
1/2 tsp garlic powder
1 can (28 oz) baked beans, undrained
1 can (16 oz) kidney beans, rinsed and drained
1 can (15 1/2 oz) pinto beans, rinsed and drained
1 can (15 oz) lima beans, rinsed and drained
1 can (15 1/2 oz) black eyed peas, rinsed and drained

In a large skillet, cook bacon until crisp. Remove to paper towel. Drain,reserving 2 tbls drippings. In the drippings (or in oil if not usingbacon) saute onions until tender. Add brown sugar, vinegar, salt,mustard and garlic powder. Bring to a boil. In a slow cooker, combinebeans and peas. Add onion mixture and bacon; mix well. Cover and cookon high for 3-4 hours or until heated through. (I've always just useda pan on top of the stove and cooked for about 45minutes -1 hour).
