1/4 cup cheese (combination of mozzarella, Parmesan, and provolone), shredded
Salt and pepper
Preheat oven to 350 degrees F.
Place tomatoes that have been cut in half on a baking sheet.
Place remaining ingredients in a mixing bowl and toss gently. Salt and pepper, to taste.
Place crumb mixture over the top of each tomato half, and press gently.
Bake the tomatoes for 20-30 minutes, or until the tomatoes are slightly soft and the crumb mixture is crisp. Place under the broiler for a minute or two if the tomatoes are cooked, but not golden brown.
