Preheat oven to 375°F.
Cut top off tomato and hollow out with melon baller (do not discard the top - it’ll be the “hat” while for the tomato during cooking). Toss hollowed out tomatoes with salt, pepper and olive oil, then place in small baking dish. Set aside.
Preheat sauté pan, and add olive oil. Once oil is hot, sauté onions, garlic, dried herbs, salt and pepper in for 2 minutes.
Combine ground beef, milk and sautéed onion mixture in a mixing bowl.
Form ground beef mixture into four large meatballs, then stuff meatballs into hollowed out tomatoes. Place tomato “hat” on top of ground beef. Roast for 30 minutes. Enjoy with a simple green salad!
