Different things for different meats. Wife made Italian subs the other night, Olive oil, balsamic vinegar, salt, pepper and oregano.
Lots of time a ham sandwich will just get the bread buttered.
Bologna gets Dukes and Crystal hot sauce.
Turkey gets a little Dijon, or Dukes and sometimes Chipotle Aioli. Chipotle Aioli also goes on fish sandwiches.
