Fishstick
Fishsticks were a type of food eaten by Humans, made from processed fish meat that was formed into short "sticks" and coated with breadcrumbs or similar ingredients. These could then be frozen and quickly reheated for convenient meals, known as TV dinners. It is usually available in the freezer aisle of grocery stores.
Frozen fish sticks were among the elements of Human culture Stron sarcastically suggested were among Mestral's list of "thing(s) they have to offer" during the marooned Vulcans' stay on Earth in 1957. (ENT: "Carbon Creek")
