1 onion, finely chopped by hand or food processor* (about 1 cup)
1 green bell pepper, finely chopped by hand or food processor* (about 1 cup)
2 Tablespoons granulated sugar
2 Tablespoons prepared yellow mustard
1 Tablespoon white vinegar
1 teaspoon salt
¾ cup ketchup (or a little more if needed, but don't make too runny; you want it thick)
Warmed hamburger buns, to serve
**the original recipe says to grind the onion and pepper, but I found that finely chopping or using a food processor work fine.
Instructions
In a large skillet over medium high heat cook and stir the meat until no pink remains, breaking up with a spoon as you stir, Add remaining ingredients and mix well. Reduce heat to low, cover and simmer for 25-30 minutes, stirring occasionally.
Serve meat hot in warmed hamburger buns.
