Crisp garlic-rubbed Italian bread meets a rich coastal topping of tender mussels, littleneck clams, and sweet shrimp simmered in white wine and ripe plum tomatoes. Infused with fragrant olive oil, fresh parsley, and a gentle kick of crushed red pepper, each bite balances crunchy toast against savory seafood broth. Easy enough for casual entertaining yet impressive on any platter, this warm appetizer comes together in one hour.
