In a skillet over medium heat, cook your ground beef with the finely chopped onion and minced garlic until the beef is browned and the onions are soft, about 5-7 minutes.

Mix in the tomato sauce or ketchup, Worcestershire sauce, chili powder (if using), and season with salt and pepper. Simmer for 5-7 minutes until it thickens, then remove from heat.

Preheat your oven to 400°F or set the broiler for preferred crispiness.

Spread a thin layer of butter on each slice of bread, then arrange on a baking sheet.

Evenly distribute the Sloppy Joe mixture over each slice of bread.

Pile on the shredded cheddar cheese on each slice.

Bake or broil for 5-7 minutes, keeping a close eye to avoid burning.

Serve warm, optionally garnishing with chopped parsley or green onions.
