From ATK of course (they added an extra garlic clove and used water and tomato sauce, I just added extra tomato purée)
Warming don't overcook the meat in step one. You want it to be pink and then cook in the sauce.
2 tablespoons vegetable oil
1 medium onion , chopped fine
1/2 teaspoon table salt
1 cloves garlic
1/2 teaspoon chili powder
1 pound 85 percent lean ground beef
Ground black pepper
1 teaspoon brown sugar
1.5 cup tomato puree
1/2 cup ketchup
1/4 teaspoon hot pepper sauce
4 - 6 hamburger buns
1. Heat oil pan. Add onion and salt cook over medium heat, stirring occasionally, until onion is soft, about 10 minutes.
Add garlic and chili powder and cook until fragrant, about 30 seconds. Add beef and cook about three minutes.
2. Add 1/4 teaspoon pepper, brown sugar, tomato puree, ketchup, water, and hot sauce. Simmer until Sloppy Joe sauce is slightly thicker than ketchup, 10-14 minutes. If it cooks longer, you might need to add more water to thin it out.
