I make this at least once a week. Tomatoes are even better for you when they are cooked. It enhances their nutrition. Since my husband's heart attack last year, I serve him lots of tomatoes. I have done these on the grill and in the toaster oven (when it's too cold outside to cook) and I have made it so many different ways, by changing the type of cheese I use to actually hollowing out the tomatoes and stuffing them with the ingredients. When I make them, I usually sprinkle a little home made chili powder on his because he likes his spicier, I like mine just plain. (I didn't add the chili powder in the recipe as it's a home made blend of whatever peppers were growing in our garden last year that I dehydrated and ground up) Sometimes, we have had these with no other cheese except for the feta and it is still very good. Just adjust the recipe to your likings and see what you can come up with!
