Arrange 4 slices, buttered side down, on clean work surface. Divide cheese evenly among 4 slices of bread. Arrange tomato slices over cheese, cutting slices in half to fit if necessary. Scatter basil leaves over tomatoes. Top with remaining slices of bread, buttered side up. Place sandwiches on a medium-hot grill, off direct heat.

Turn sandwiches over, and continue grilling until bread is golden and cheese is completely melted. Move to a slightly cooler part of the grill to melt if bread is darkening too much.
