While the pasta boils: Pulse about 3 slices of country-style bread (crusts removed) in a food processor until they are coarse crumbs. Warm a few teaspoons of olive oil in a sauté pan and add bread crumbs. Cook, stirring until crumbs are lightly golden; add 5 chopped garlic cloves and continue cooking another minute or 2. Season with salt and pepper. Drain pasta, toss lightly with olive oil, stir in bread-crumb mixture and finish with minced, fresh parsley.
