Sausage-and-Broccoli Rabe Variation: Replace chorizo with 8 ounces Italian sausage, casings removed, broken into pieces. Cook until opaque, about 3 minutes. Replace water with 3/4 cup chicken stock. Replace clams with 6 ounces broccoli rabe, cut into 2-inch pieces (5 1/2 cups) and tossed with 1 tablespoon water and 1/4 teaspoon coarse salt. Stir once removed from oven.
