On-the-Go Sloppy Joes

Sloppy Joes
*3 lbs. ground beef
*1 1/2 c. ketchup
*3 T. brown sugar
*2 tsp. dry or regular mustard
*2 T. apple cider vinegar
*2 1/2 tsp. salt (that's quite a bit, use less if desired)
*1/4 tsp. pepper
*1 tsp. worcestershire sauce
*1 can tomato soup
***Brown hamburger.  Mix all ingredients and let simmer 15 to 20 minutes.  Fills 20 buns.

This is a great recipe to make and then freeze in portions.  When ready to use just reheat and fill buns.
