Marinate tomatoes in balsamic vinegar for 30 minutes. Lay on a baking sheet, season with salt and pepper. Bake for 7 minutes at 350 degrees. Then top with sautéed spinach and mozzarella. Broil until cheese melts.
This is one of my favourite Friday night recipe. It's so tasty and easy to make. You can serve it as a meal or an appetizer. Your guests will really enjoy this Sausage Stuffed Portobello Mushroom Recipe.
