Place the bread on a baking sheet and broil, turning once, until lightly toasted on both sides, about two minuted total. Remove from the broiler and immediately rub one side of each slice with the garlic cloves.
Arrange the grilled bread, garlic side up, on a serving platter, and spoon on the tomatoes, dividing evenly. Serve at once.
