                Preheat your oven to 375°F. Cut the tops off the bell peppers and remove the cores and seeds. Place the hollowed-out peppers cut side up in a baking dish or on a rimmed baking sheet. The dish should be deep enough to keep the peppers upright during baking.

                Heat the olive oil in a large skillet over medium heat. Add the diced onion and sauté until soft and translucent, about 3-4 minutes. Add the minced garlic and cook for about 1 minute more, stirring frequently to prevent burning.

                Add the ground beef to the skillet with the onions and garlic. Break up the meat with a wooden spoon and cook until no longer pink, about 5-6 minutes. Drain excess fat if necessary.

                Stir in the cooked brown rice, diced tomatoes (with their juice), tomato paste, dried oregano, and smoked paprika. Mix well to combine all ingredients. Cook for about 4-5 minutes, stirring occasionally, until the sauce is slightly reduced and thickened. Taste and season with salt and pepper as needed.

                Using a spoon, fill each hollowed-out bell pepper with the beef and rice mixture. Pack the filling in gently but don't press too firmly. The peppers should be filled completely to the top.

                Place the stuffed peppers in the preheated oven and bake for 10-12 minutes, until the peppers begin to soften and become slightly tender but still hold their shape.

                Remove the baking dish from the oven and sprinkle the shredded cheddar jack cheese evenly over each stuffed pepper. Return to the oven and bake for an additional 5-7 minutes, until the cheese is completely melted and starting to bubble and turn golden at the edges.

                Remove the stuffed peppers from the oven and let them rest for 5 minutes. Sprinkle with freshly chopped parsley before serving. Enjoy while hot!
