Barbeque beef and pork

1 1/2  pounds        Stewing meat -- cubed
   1 1/2  pounds        pork -- cubed
   2      cups          Onions -- chopped
     1/2  cup           Brown sugar -- firmly packed
   3      teaspoons     Chili powder
   2      teaspoons     Salt
   1      teaspoon      Dry mustard
     1/4  cup           Vinegar
   2      teaspoons     Worchestershire sauce
   6      ounces        Tomato paste
  16                    Sandwich buns

     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. *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. Lisa Crawley
