Grilled Bread with Olive Oil, Tomato, and Parmesan Cheese

This bruschettà, slightly more elaborate than the traditional garlic toast, includes tomato and cheese. If you are grilling outside, toast the bread right over the coals. Otherwise a hot oven will work fine. (If you have a fireplace, consider setting a low grill over the coals and cooking indoors.) A large country loaf, coarse-grained and full of flavor, makes the best toast.
