Meats: beef (preferably tri-tip), chicken (wings, tenders, breast cutlets), and pork (shredded, baby back ribs, ham). Processed meats include stuff like pepperoni, prosciutto, and salami.
Cheese: cheddar, parmesan (includes the real deal from Italy, parmesan-like imitations made elsewhere, and the fake stuff by Kraft), most mozzarella varieties (brined, low moisture, whole milk, part skim, smoked, marinated, covered in Italian herbs, etc) except for burrata, provolone, gouda (regular or smoked, I’m also a big fan of Boar’s Head’s chipotle gouda), Colby Jack (Boar’s Head has a nice 3-pepper Colby Jack that’s
really good), and most blue cheeses. I’m also a fan of
Sartori Cheese’s BellaVitano cheese (their site describes its flavor profile as being a combination of parmesan and cheddar), especially their black pepper BellaVitano and their Italian herb BellaVitano.
Bread: I prefer sourdough as an all-purpose bread unless it’s for a sweet dish (I go for brioche when it comes to stuff like French toast) but if I’m trying to mimic a sub sandwich I go for the french bread, bolillo rolls, or telera rolls you can find in supermarket bakeries.
