Add your onion to the ground beef and sautee it.
This breaks the onion down so that you get a lot of flavor, but not a lot of onion-y chunks. My kids don't like onion-y chunks and I assume your children are as picky as my children. Please don't correct me if I'm wrong.
Then add 3 small cans of tomato sauce, 1/3 of a cup of ketchup, dash of salt and pepper, 1/2 tsp garlic powder and 2 tablespoons of brown sugar. *More or less sugar as desired.*
Serve on buns or sliced bread. This is also good on rice or baked potatoes!
Add a slice of cheese for a Sloppy Joe Melt. It makes you fancy.
2 lbs browned hamburger meat
1/2 cup finely diced onion
3 small cans of tomato sauce
1/3 cup ketchup
2 Tbl brown sugar
1/2 tsp garlic powder *optional*
dash salt and pepper
Saute the onions with the browned hamburger meat for a few minutes until translucent, then add the remaining ingredients. Simmer the mixture on low for 5-10 minutes until the mixture starts to thicken.
Serve on rolls or sliced bread.
