Grilled Steak with Arugula and Shaved Parmesan

(Bistecca ai Ferri con Rucola e Parmigiano)

Bistecca ai ferri (beefsteak grilled over the fire) is sometimes called bistecca alla fiorentina; it is the signature dish of Florence, but the people of Cortona, in eastern Tuscany, also claim it as theirs. No matter where it's from, grilled steak is perhaps the most classic and luxurious Tuscan beef dish. Any succulent, thick-cut steak will do, although Tuscan chefs prefer porterhouse or T-bone, especially from their local Chianina cows. The meat is coated in oil and garlic, then grilled and served on a bed of arugula with lemon wedges and shaved Parmesan. Use only genuine Parmigiano-Reggiano cheese; a vegetable peeler makes it easy to shave thin, curling strips.
