Set a large pot over medium low heat. Add a few drops of olive oil or vegetable oil and sauté the garlic for a minute or two until just fragrant and very light golden brown. Add ground beef increase heat to medium/medium-high, and cook until no longer pink breaking apart and stirring as meat cooks. Drain grease from meat.
While meat is browning, make sauce. In medium bowl, stir together tomato sauce, ketchup, brown sugar, Worcestershire sauce, mustard, garlic powder, onion powder, and freshly ground pepper, until well combined. Pour over browned meat, stir, and simmer for a few minutes until heated through or longer, if you have time, to allow the flavors to meld.
Serve on hamburger buns or rolls with sliced Pickles on top.
Notes
If you like your sloppy Joe meat with onions and peppers, you can dice up half an onion and half a pepper and add them towards the end of browning the beef.
