"Salads of tuna, tomatoes and roasted peppers are as abundant in Spain as tuna with mayo is in the United States. This is a molded tuna masterpiece, layered with slightly sweetened tomatoes and dolled up with basil and black olive puree. Serve it as a part of a tapas spread or as a luncheon salad with grilled country bread and have the recipe ready to hand out. The basil puree and the tomatoes can be prepared a day or even two ahead (the tomatoes need to sit about an hour). For molding the salad use a pie plate or experiment with a loaf pan or bowl, or make individual portions using ramekins or souffle cups. Adapted from the cookbook, "The New Spanish Table"...."
