Pirate Stew

3/4 cup chopped onion
1 lb. ground beef
1/4 cup uncooked, long grain rice
3 cups diced raw potatoes
1 cup diced celery or carrots
2 cups canned kidney beans, drained
1 tsp. salt
1/4 tsp. pepper
1/4 tsp. chili powder
1/4 tsp. Worcestershire sauce
1 cup tomato sauce
1/2 cup water
1 small jar canned tomatoes - optional (I used canned tomatoes as the above recipe seemed to dry and not enough sauce)

Brown onions and ground beef. Drain. Layer ingredients in slow cooker in order given. Cover. Cook on low 6 hours or until potatoes and rice are cooked.
