Crockpot beef and beans

This was from my week with a crockpot theme. It was good for a change and would make a good potluck dish!

INGREDIENTS:
1 to 1 1/2 pounds lean ground beef
1 tablespoon olive oil
1 cup chopped onion
1/2 cup chopped green bell pepper
2 large cans (28 ounces each) baked beans
2 cans (8 ounces each) pineapple tidbits or chunks, drained
1/2 cup barbecue sauce
Dash cayenne pepper
PREPARATION:
In a large skillet, heat olive oil over medium heat. Add ground beef, onion, and bell pepper; fry until ground beef is no longer pink.
Combine the ground beef mixture with the remaining ingredients in the slow cooker. Cover and cook on LOW for 6 to 8 hours or HIGH for 3 to 4 hours.Serves 6 to 8.
