What ingredient is not typically found in the Totally Tuna?

The ingredient that is not typically found in the Totally Tuna sandwich is turkey. Totally Tuna primarily consists of a tuna salad mixture, which often includes ingredients like mayonnaise and seasoning, along with fresh vegetables such as cucumbers and lettuce. The absence of turkey is notable since the sandwich is designed to highlight the flavor of tuna, making it a clear choice for those who prefer a seafood sandwich over a poultry option. This is why turkey does not belong in the traditional recipe for Totally Tuna, as it would alter the intended flavor profile and composition of the dish.
