Tuna Salad Sandwich


3 cans tuna (5 ounce each); dry the liquid
3 tablespoons parsley leaves, chopped
4-5 tablespoons green onion, chopped
1 tablespoon Worcestershire sauce
1/2 teaspoon onion salt
2 sardine (from the can and minced)
1 tablespoon lemon juice
12 tablespoons sour cream
1/3 cup mayonnaise


  • In a large bowl combine all ingredients and mix everything lightly.
  • Use soft breads or rolls to prevent salads from squeezing out of sandwiches, or use hot-dog type roll that is not open on all sides.
  • Line the bread or roll with lettuce to keep it from absorbing too much moisture.
  • Fill breads or rolls with prepared mixture and serve immediately.

Tuna are several species of ocean-dwelling fish in the family Scombridae, mostly in the genus Thunnus. Tuna are fast swimmers and like most other fish species are cold-blooded. Unlike most ocean fish species, which have white flesh, the flesh of tuna is pink. This is because the tuna's blood has a higher oxygen carrying ability than other fish species. Some of the larger tuna species such as the bluefin tuna can raise their blood temperature above the water temperature with muscular activity. Though not really warm-blooded, this enables them to live in cooler waters and survive a wider range of circumstances.

Tuna is a popular seafood. Some varieties of tuna, such as the bluefin, are endangered because of overfishing, while others are part of well maintained fisheries, such as the bigeye or yellowfin.

Mercury levels are oftentimes relatively high in tuna, as they sit higher in the food chain.

It is difficult to keep tuna in a captive environment; Monterey Bay Aquarium is one of the few aquariums in the world that successfully keep tuna in display.
