(NEXSTAR) – If ever there were a day to ingest all of your meats, cheeses and veggies via some type of bread-based vessel, this is it.

Friday, Nov. 3 marks National Sandwich Day, a quasi-holiday established to justify every American’s burning desire to devour nothing but sandwiches at nearly every meal. This means plenty of major sandwich chains are happy to indulge our cravings with special deals and discounts on all manner of sammies, subs, grinders and hoagies on Friday.

In the mood for a sandwich? Of course you are. Take a look at the National Sandwich Day deals below, then cancel any non-sandwich lunch engagements you may or may not have previously scheduled.

Capriotti’s Sandwich Shop

On Friday, customers at Capriotti’s can get a free small sub with the purchase of another sub of any size. The offer can be found via the chain’s CAPAddicts app.

Firehouse Subs

This National Sandwich Day, Firehouse Subs will be donating a portion of the sales from its King’s Hawaiian Pork and Slaw Sandwiches to a Hawaii disaster relief fund established by the Firehouse Subs Public Safety Foundation. The sandwich is available for a limited-time, and a portion of all sales — not just on National Sandwich Day — will go toward the fund.
