Preparing the filling: To do this, grate the cheese on a large or small grater (as you prefer).
Place the grated cheese in a deep container, add mayonnaise and egg, add salt and pepper to taste (or other spices of your choice).
Pass the garlic through a press, add to the filling, mix until smooth.
Cut the tomatoes in half and place them in a baking dish. Place the filling on each half of the tomato and bake in the oven, preheated to 180 ℃ for 5-7 minutes. Serve the finished tomatoes hot.
