From Ina Garten. She says this is a nice way to give grocery store tomatoes that yummy summer flavor. It's a very flavorful tomato dish, made with a garlicky pesto (if using her homemade recipe - but you could also use store bought), so she recommends pairing it with something mild like fish. *prep time does not include making your own pesto. Note: Make sure to slice your tomatoes at least 1/2 inch thick.
