In Italy, a juicy hunk of aggressively seasoned, boned-out, slow-roasted pig with cracklings, sliced and served on a roll, is considered fast food. It can now be found at Porchetta, an East Village takeout shop where chef-owner Sara Jenkins supplements the main attraction with beans, cooking greens, crispy potatoes, mozzarella sandwiches, and her own biscotti. 110 E. 7th St., nr.
