This Mediterranean-inspired panzarella is full of rich butter beans and oil-packed tuna for a salad that is as exciting as it is filling.
Tear bread into 1-inch pieces. On a rimmed baking sheet, drizzle bread with 2 tablespoons olive oil. Toast at 400 degrees until golden, about 10 minutes. Combine bread, onion, pickle, basil, beans, and tuna. Toss with pickle brine and 1/4 cup olive oil; season.
