Again this is from the cookbook Best Loved Slow Cooker Recipes
3 to 4 pound boneless beef pot roast

1 onion, sliced
2 tbs all-purpose flour
1 tbs prepared mustard
1 tbs chili sauce
1 tbs Worcestershire sauce
1 tsp vinegar
1 tsp sugar
Trim all excess fat from roast. Place potatoes and onion in the bottom of a crock pot.
Make a smooth paste with flour, mustard, chili sauce, Worcestershire sauce, vinegar and sugar. Spread over top of the roast.
Place roast in crock pot on top of potatoes and onions.
Cover and cook on low for 10 to 12 hours or on high for 5 to 6 hours
