If you have a garden your tomatoes should be ready to eat. If they are not then you can go to your local farmers market and buy some. My tomatoes are not quite ready so I went and bought some at my farmers market.
Preheat your gas grill and then turn it to medium heat
Cut your tomatoes in half crosswise. Lay the cut side up on a large baking sheet and brush the cut side with olive oil and sprinkle with salt and pepper.
Lay the oiled side down on the grill an close the lid. You will want to grill for about 5 minutes.
Brush the other side with the olive oil and sprinkle with salt and pepper and grill for about 5 minutes.
You will want to serve hot and enjoy your fresh grilled tomatoes.
