Preheat the oven to 375 degrees F (190 degrees C).
Mix together tomatoes, olive oil, garlic, parsley, basil, oregano, salt, and pepper in a large bowl, working the seasonings into cavities of tomatoes. Place tomatoes, cut-sides up, on a baking sheet. Sprinkle each tomato with about 1 tablespoon feta cheese.
Bake in the preheated oven until tomatoes are cooked but still firm, about 15 minutes.
