1. Heat a large skillet over medium-high heat. Add olive oil if using lean beef, then add ground beef. Cook for 4–5 minutes, breaking it up, until browned. Drain excess grease if needed.

2. Add diced onion and sauté for 2–3 minutes until soft. Stir in garlic and cook for 30 seconds.

3. Lower heat to medium. Add ketchup, tomato paste, Worcestershire sauce, mustard, brown sugar, and smoked paprika. Mix well, season with salt and pepper, and let simmer for 5–7 minutes until thickened.

4. While the meat simmers, toast your buns using a skillet or toaster with butter or mayo until golden.

5. To assemble, optionally place lettuce on the bottom bun, top with a generous scoop of Sloppy Joe mixture, then cover with grated cheddar cheese. Place the top bun and serve hot.
