Sloppy Joe Sliders

I was going to make these when we were getting together with friends but at the last minute that got cancelled so I just made them for dinner for my family.  There wasn't a single one left! They devoured them them all and my son was sad there weren't more.  My 2 year old called them "fluffy joes" which kept us laughing all through dinner too.  This recipe was adapted from Valerie's Kitchen.

1lb ground beef
1/2 cup chopped onion
8oz can tomato sauce
1/2 cup ketchup
2 tsp Worcestershire sauce
2 tsp mustard
2 tsp brown sugar
1 tsp garlic powder
1/2 tsp cumin
12 slider buns
1 cup cheddar cheese
2 tbsp melted butter
1/2 tsp sesame seeds

Heat oven to 350. Cook the ground beef and onions in a skillet.  Drain off the grease. Stir in the tomato sauce, ketchup, Worcestershire sauce, mustard, brown sugar, garlic powder and cumin.  Let it simmer for 10 minutes. Place the bottom half of the buns in a 9x13 baking dish. Spoon the sloppy joe meat onto each bun. Sprinkle with cheese. Top with the other half of the bun then brush with butter and sprinkle with sesame seeds. Bake for 10-12 minutes.
