Toast the bread in a toaster or oven until it is very brown.
Immediately after removing the bread from the toaster, rub a garlic clove over the entire surface of 1 side. Each slice should use up about 1/4 to 1/3 of a clove. (Be careful, when the garlic meets the toast's hot surface, it will create fumes that sting your eyes, just like an onion.)
Generously drizzle olive oil over the top of each slice. Sprinkle with salt and a generous amount of pepper. Top with 1 or 2 slices of prosciutto. Slice into 1-inch strips, or quarters, and serve immediately.
