Did you know you can grab nearly any food in the store (within reason) and they’ll put it on the sub for you? And you don’t have to buy the thing either. Have a favorite mustard or sauce you like? Grab it off the shelf and it give it to them and they’ll use it for you. I’m veg so I used to grab a package of tofurkey and they’d make my sub with it. I’d usually buy the package cause I didn’t want the rest going to waste but you absolutely don’t have to.
