In a bowl, mix the halved tomatoes and chopped garlic, parsley, basil, and oregano. Add the olive oil, salt, and pepper, stirring well so that the seasonings work deep into the tomatoes’ grooves.
Place the tomatoes on a baking sheet, cut sides up. Sprinkle about one tablespoon of feta cheese on each tomato.
Bake the tomatoes for about 15 minutes. They should be cooked through but still firm to the touch.
