Amish Hamburger BBQ

2 lb ground beef
1 large onion peeled & chopped
1 cup ketchup
3 Tablespoons brown sugar
3 tablespoons vinegar

3 teaspoons yellow mustard                                                          
1 Tablespoon worcestershire sauce
1 teaspoon parsley
1 teaspoon chopped garlic or garlic powder

Lightly brown the hamburger then add chopped onion. Continue browning until meat is no longer pink & onion is soft. Add remaining ingredients & cook on medium heat, stirring often until meat is thoroughly cooked & sauce is thick & bubbly. This should take about 1/2 hour. Or you may brown the meat & onion then combine all ingredients in a crockpot & cook on low approx. 4 to 5 hours. Serve on your favorite rolls with your favorite cheese slice on top of the BBQ ! Very good sweet & sour BBQ! Taste even better the next day.
