Cut tomatoes in half lengthwise, and place, cut sides up, on a baking sheet. Sprinkle evenly with salt and pepper to taste, Italian seasoning, and Feta cheese. Drizzle evenly with Italian dressing. Broil 3 inches from heat for 2 to 3 minutes or just until cheese starts to brown. Try adding bacon bits, black olives, mushrooms, or whatever you like to change up the recipe.
