A sloppy joe is a sandwich with ground beef in a sweet sauce.
If you want to do this meal the right way, be sure to include Tater tots on the side.
Adding onion and green peppers might give it a little crunch, which would be the two things I would not object to adding. I wouldn’t add ketchup or other spices like chili powder or crushed red pepper. The key to this recipe is the tomato sauce with brown sugar to give it that sweet flavor.
