In a large skillet, over medium high heat, brown your ground beef until no longer pink. If necessary, drain off any grease.
To the slow cooker, add the browned beef, diced onion, bell peppers, garlic, ketchup, water, brown sugar, chili, mustard and hot sauce.
Stir to combine and cover.
Cook on LOW for 4-6 hours.
Serve on hamburger or brioche buns.
