These are delicious, you could use any combination of these fillings but this worked very well.
Cut the tops off the tomatoes and scoop out the middle. Discard. Mix together some breadcrumbs, grated cheese, pinenuts, sunflower seeds, pesto and tomato tapenade. Use to fill the tomatoes, overfilling slightly to make a domed top and pop the lid on. Bake for 10 minutes at 200 degrees.
