Instructions
1. In a large skillet over medium-high heat, cook the ground beef until browned, breaking it up with a spoon. Drain any excess fat.
2. Add the chopped onion and green bell pepper to the skillet and cook until softened, about 5-7 minutes.
3. Stir in the tomato sauce, crushed tomatoes, chopped pepperoni, tomato paste, dried oregano, garlic powder, and red pepper flakes (if using).
4. Bring the mixture to a simmer, then reduce heat to low, cover, and let it cook for at least 15-20 minutes, allowing the flavors to meld. Stir occasionally.
5. Season with salt and black pepper to taste.
6. Spoon the pepperoni pizza sloppy joe mixture generously onto the lightly toasted hamburger buns. Top with shredded mozzarella cheese.
7. For an extra cheesy experience, you can place the assembled sloppy joes under a broiler for 1-2 minutes, or until the cheese is melted and bubbly.
Short Tips
* **Spice it Up:** Add a pinch more red pepper flakes for an extra fiery kick, or a dash of your favorite hot sauce.
* **Veggie Boost:** Feel free to add other finely diced vegetables like mushrooms or black olives for extra flavor and nutrients.
* **Make Ahead:** The sloppy joe mixture can be made a day in advance and reheated on the stovetop for a quick meal.
* **Garlic Bread Buns:** For an even more intense pizza flavor, lightly spread garlic butter on your buns before toasting.
* **Open-Faced:** Serve these as open-faced sloppy joes on a single bun with extra cheese and broiled for a melty, delicious treat.
