SLOW COOKER SLOPPY JOES
1 med. onion
2 ribs celery
2 # extra-lean ground beef
2 cups tomatoe sauce (I used the canned)
1/4 c white vinegar
3 tsp worcestershire sauce

1/2 tsp pepper
Peel the onion and chop it into 1/4 inch pieces. Chp the celery into 1/4 inch pieces. Put the onion, celery, and ground beef in a med sized skillet on med high heat and brown until meat is no longer pink. Drain off any fat.
Combine all ingredients in the lsow cooker. Cook covered on low setting for 2-3 hours. (Mine cooked 3 3/4 hours and was fine.)
Served it over burger buns, had some carrots, peppers and tomato cut up and a bit of cheese cut up...dinner was simple and good!
