In a large skillet, brown the 1 pound ground beef. Drain well and set aside.
In the same skillet, melt the 1 tablespoon butter and add the 2 tablespoons onion and 1 clove garlic, sauté until soft, approximately 2-3 minutes. Remove to a large mixing bowl.
In the large mixing bowl, combine the cooked ground beef, cooked 1 cup white rice, onion and garlic, 1 tablespoon Worcestershire sauce , 2 tablespoons ketchup, 2 teaspoons homemade Italian seasoning, ½ teaspoon coarse Kosher salt, ¼ teaspoon ground black pepper and 2/3 cup of the cheddar cheese. Toss to combine.
Cut the tops of the 6 bell peppers, removing all the seeds and membranes.
Place the peppers in a baking or casserole dish. Fill each with the ground beef mixture.
Bake for 15-20 minutes, or until the peppers start to soften. Remove and top with the remaining 1/4 cup cheddar cheese, return to oven until cheese has melted, about 2-3 minutes.
Remove, garnish with parsley, and serve.
