Preheat broiler to 400 degrees. Slice bread into 1 inch slices and arrange in a single layer on a cookie sheet. Place under the broiler for 5 minutes, or just until toasted golden brown.
Remove toast from the oven, and, using an oven mitt or towel, hold each toast while you rub a clove of garlic over the top of the bread. The toasted bread will grab the garlic as you run it across the top, leaving your bread with garlicky goodness in it.
Place toast back on the cookie sheet and drizzle with olive oil.
Put tomatoes on the toast, split side down, and push down on the tops of the tomatoes to saturate the bread.
Sprinkle with fresh basil and top with grated Parmigiano-Reggiano. Enjoy!
