Preparation Preheat oven to 350°F. Cut off top third of tomatoes; chop tops and reserve. Scoop out seeds, juice, and pulp from tomatoes and discard. Melt butter in heavy large skillet over medium-high heat. Add onion and sauté until tender and golden, about 8 minutes. Add lamb and sauté until browned, about 7 minutes. Add chopped tomato tops, wine, mint, 2 tablespoons parsley, and cinnamon. Bring to boil. Reduce heat and simmer until mixture thickens, stirring frequently, about 12 minutes. Stir in cooked rice. Place tomatoes in 13x9x2-inch glass baking dish. Spoon lamb mixture into tomatoes. Sprinkle each tomato with 1/2 tablespoon breadcrumbs, then 1 tablespoon cheese. Bake until heated through and cheese begins to turn golden, about 25 minutes. Sprinkle with remaining 2 tablespoons parsley.
