Smoked Salmon and Cod Salad with Mixed Olives
Slice the head of lettuce into 4 pieces, and place each bunch on a large serving plate in a cross shape, without overlapping.
Place all of the chopped olives in a small bowl, and then add the olive oil, vinegar, and salt, to taste. Stir to combine, and then spread generously over the lettuce.
Place the fillets of smoked salmon and cod over each of the lettuce pieces.
