Preheat your oven to 375°F (190°C) and gather your bell peppers. Cut the tops off and remove the seeds and membranes.

In a skillet, sauté chopped onions and minced garlic for 3-4 minutes. Add ground beef and cook until browned, about 5-7 minutes. Stir in diced tomatoes, rice, and Italian seasoning.

Remove from heat and stir in shredded cheese until melted.

Carefully spoon the filling into each carved pepper, pressing down gently.

Cover and bake in the preheated oven for 30 minutes, then remove foil and continue baking for 10-15 minutes.

Use sliced olives as eyes and pepperoni as mouths for decoration.

Serve on a festive platter, sprinkle with parsley or cheese if desired.
