Preheat the oven to 350?F.
Place the sliced bread in one layer on a large baking sheet and bake until lightly browned on both sides, turning once, about 4 minutes per side. Remove the bread from the oven and rub the garlic over one side of each slice. Top each bread slice with a slice of cheese and bake until the cheese is bubbly, about 4 minutes.
