This recipe has bread crumbs, but what if you substituted the bread crumb topping with mozzarella cheese or some other topping? I personally think the tomatoes would be good with just the balsamic sauce. The nice thing about this recipe is that you can easily increase the ingredients.
Balsamic Baked Tomatoes with Parmesan Crumbs
4 large tomatoes (8 oz. each)
1/2 teaspoon salt
2 slices of whole grain bread (2 oz.)
3 tablespoons Parmesan cheese
1 teaspoon olive oil
1/3 cup balsamic vinegar
2 tablespoons light brown sugar
2 tablespoons water
1. Preheat oven to 400 degrees F. Core tomatoes and cut in half horizontally. Place tomatoes, cut-side up, in a glass baking dish large enough to hold them in a single layer. Sprinkle tomato halves with salt.
2. Place bread in food processor and pulse until fine crumbs. Combine crumbs, Parmesan, and oil in small bowl. Fill tomatoes with crumb mixture.
3. Bake uncovered, until topping begins to brown and tomatoes are heated through, about 25 minutes.
4. Meanwhile, combine balsamic vinegar, brown sugar, and water in a small skillet. Bring to a boil over high heat and cook until syrupy, about 3 minutes. Drizzle over baked tomatoes.
