These treasures of the tomato family are full of garden-fresh juiciness, sweetness, and tang. Heirlooms are actually a range of tender, old-fashioned varieties. They come in many shapes, colors, and sizes. We love to give them their moment in the spotlight all by themselves. Cut up an assortment of heirlooms, then sprinkle with a dash of sea salt and a drizzle of fruity extra-virgin olive oil.
