Preheat grill on high. Clean and oil grates. Decrease temp to low on the section used for the tomatoes but leave other side on high or close to it.
Wash tomatoes and cut tops off. Spoon out inside being careful not to go through the outside.
Wash out the shells and take the inner core that you removed and wash off any seeds.
Chop the cores into 1/4 inch cubes removing any tough parts.
In a mixing bowl, combine chopped tomato, 1/4 cup each of feta, Parmesan, and Italian breadcrumbs. Add salt, pepper, parsley. Oregano, basil, and garlic. Mix well. Stuff tomato shells.
Mix 1 tablespoon parmesan, bread crumbs, and olive oil. Top each stuffed tomato with half of the mixture.
Brush tomato skin with oil and place over low heat.
Cook with grill lid closed for about 10 minutes until skin is falling off and the top is browning. Note: Carefully remove from the grill with spatula underneath, or it may fall apart.
