Got this from my friend Ruchie. They're delicious but they definitely live up to its name! Don't make it for dinner if your in laws are around :)
1 lb meat
1 small onion
1 cup tomato sauce
½ cup ketchup
1 Tbsp brown sugar
½ tsp pepper
Brown the meat together with the onion. Pour away the liquid.
Add rest of ingredients and mix.
Let boil and cook on low flame for 20 minutes.
