Colorful tropical fruit contrasts with slightly bitter salad greens and fresh tuna steak to make a refreshing main-dish salad. Good-quality tuna is key to the success of this recipe. The secret to buying fresh fish is to ask to smell it: the tuna should smell briny, clean and fresh, like the ocean on a spring morning, not like the tidal flats on a hot summer afternoon. Do not use fresh pineapple juice, which has an enzyme that "cooks" the fish as it marinates.
