Primary meat

[Cami]

[Primary Meat] (n) is defined as the main meat ingredient in a sandwich.
The term identifies the defining meat on an individual sandwich and does not characterize a meat on its own merits. For example, in a [BLT] bacon is the [primary meat]; on a turkey club, bacon is not the primary meat.
The Primary Meat on a sandwich may or may not determine the name of the sandwich:
A Turkey Club is named for its Primary Meat, but an [Italian Club] is named for the collective ingredients of the sandwich, not a singular Primary Meat.
