1 For Seafood and Poaching Liquid:
2 Place the following in the bottom of a large saucepan; carrot, celery, onion, bay leaf, lemon juice, salt, and peppercorns; cover with water. Place colander insert in pan, bring seasonings to a slow simmer and cook for 15 minutes.
3 Place the scallops in the colander and cook for about 3 minutes, or until opaque. While scallops are cooking, fill a large bowl with ice and cover with water. Remove scallops from poaching liquid and plunge the them into the ice bath to stop the cooking process and drain. Place in large bowl. Poach the calamari for 2 to 3 minutes, or until done. Repeat the the ice bath and drain. Add to bowl with scallops. Lastly, poach the white fish until it flakes and is cooked through, about 3 to 4 minutes. Drain and add to the bowl with the scallops and calamari.

Place celery, tomatoes, olives, parsley, basil, red pepper flakes, beans, salt and pepper in the bowl with the drained seafood. Pour dressing over the seafood salad and gently toss until well coated. Chill for at least 2 hours before serving.
6 Once chilled, place salad greens on a serving platter or individual plates and spoon seafood over greens. Drizzle with olive oil, if desired. Serve.
