Ingredients:

  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   1 1/2  pounds        beef stew meat -- cubed
   1 1/2  pounds        pork -- cubed
   2      cups          onions -- chopped
     1/2  cup           firmly packed brown sugar
   3      teaspoons     chili powder
   2      teaspoons     salt
   1      teaspoon      dry mustard
     1/4  cup           vinegar
   2      teaspoons     Worcestershire sauce
   1      6 oz can      tomato paste
  16                    sandwich buns

Preparation:

In a crockpot, combine all ingredients except the buns. Cook on low setting for 8-10 hours or til meat if tender. Stir with fork to break up pieces. Serve on buns.

NOTES : You may use all pork or all beef. I found that the pork will cook faster than the beef, so I start the beef ahead of time then add the pork.
