- 3 tablespoons olive oil
- 2 pounds sea scallops
- 2 pounds large shrimp, peeled and deveined
- 1 pound calamari rings
- 24 mussels, cleaned and debearded
- 24 littleneck clams, scrubbed and rinsed
- 3 (14.5 ounce) cans crushed tomatoes

- Heat 3 tablespoons olive oil in a large skillet over medium heat; cook and stir sea scallops, shrimp, and calamari rings in the hot oil until scallops and calamari are opaque and shrimp are pink, about 5 minutes.
- Bring a separate pot of water to a boil and add mussels and littleneck clams to the boiling water; cook until shells have opened, about 3 minutes. Remove shellfish and rinse with hot water.
- Pour crushed tomatoes, water, 2 cans chopped clams, 1/4 cup olive oil, onion, red pepper flakes, garlic, oregano, parsley, and salt into a large pot and bring to a boil. Stir cooked scallops, shrimp, calamari, mussels in shells, and littleneck clams in shells into tomato mixture. Reduce heat to low and simmer for 1 hour.
