Making your own Smoked Stuffed Pizza Meatloaf is simple when you follow these steps:

1. Prepare the Smoker: Preheat your smoker to 225°F (107°C) using your favorite wood chips.
2. Mix Meatloaf Ingredients: In a large bowl, combine the ground beef, Italian breadcrumbs, egg, Italian seasoning, garlic powder, onion powder, salt, and black pepper. Mix until well combined.
3. Shape the Meatloaf: On a piece of parchment paper, shape the meat mixture into a rectangle about 1 inch thick. Aim for a size that will be easy to fill and roll up.
4. Add Fillings: Spread pizza sauce over the center of the meat mixture, leaving a border. Layer the shredded mozzarella cheese, pepperoni slices, and diced bell peppers (if using) on top of the sauce.
5. Roll the Meatloaf: Carefully lift the parchment paper to start rolling the meat into a log, encasing the filling inside. Use your hands to ensure it holds its shape as you roll.
6. Seal the Ends: Pinch together the ends to prevent filling from leaking, and shape the meatloaf into a smooth, cohesive form.
7. Prepare for Smoking: Brush the outside of the meatloaf lightly with olive oil, and consider adding additional seasonings or cheese on top if desired.
8. Place in Smoker: Gently transfer the meatloaf into the smoker and cook for about 1 hour and 15 minutes, or until it registers 160°F (71°C) internally on a meat thermometer.
9. Rest the Meatloaf: Once cooked, remove the meatloaf from the smoker and let it rest for 10-15 minutes. This will help retain its moisture and make it easier to slice.
10. Slice and Serve: Carefully cut the meatloaf into thick slices, exposing the gooey filling inside and present it on a serving platter.

Following these steps will set you on the path to creating a delightful Smoked Stuffed Pizza Meatloaf that your friends and family will love!
