Sloppy Joes

I'm giving total credit to my boyfriend for this recipe. He likes cooking as much as I do; one day he decided to make Sloppy Joes but he revamped the recipe he found and they were the best Sloppy Joes I ever had.

1 pound ground beef
1/4 cup onion, chopped
1/4 cup green pepper, chopped
1/2 tsp garlic powder
1 tsp yellow mustard
1/2 cup ketchup
1/2 cup BBQ sauce (he uses Sweet Baby Ray's)
2 tsp brown sugar
salt and pepper to taste
hamburger buns

In a skillet over medium heat, brown the ground beef, onion and green pepper. Drain the liquids. Then stir in the garlic powder, mustard, ketchup, BBQ sauce and brown sugar. Reduce the heat and simmer for 30 minutes. Season with salt and pepper to taste.
