• Fresh basil leaves, for garnish, optional
Cut 2 tomatoes in half crosswise. Place a box grater in a shallow bowl and grate the tomato flesh from the cut sides, pushing through the large holes. You should have 1 cup or so of coarse tomato purée. Set purée aside, and discard tomato skins.
Cut remaining large tomatoes into 1/4-inch slices. Cut cherry tomatoes in half. Set aside.
Toast the bread until nicely browned and crisp. (Toasting over a charcoal grill yields a rich, smoky flavor, but a toaster, toaster oven or broiler works just as well.)
With your fingers, rub the top of each toast with a garlic clove. You will see the cloves get smaller as the garlic is dispersed, pushed into the bread. (For a less garlicky toast, press lightly when rubbing.)
