Grate 1 tablespoon peel and squeeze 1 tablespoon juice from lemon. Mince 1 clove garlic. Combine minced garlic, lemon peel and pepper; press evenly onto beef steaks. Place steaks on grid over medium, ash-covered coals. Grill, covered, 11 to 16 minutes (over medium heat on preheated gas grill, covered, 11 to 14 minutes) for medium rare to medium doneness, turning occasionally.
Meanwhile, prepare Salsa Verde. Place remaining 2 cloves garlic in food processor container. Cover; process until finely chopped. Add lemon juice, parsley, capers and olive oil. Cover and process until well blended, stopping and scraping side of container as needed.
Carve steaks into slices and season with salt, as desired. Serve with Italian Salsa Verde.
