>The only reason to go to Potbelly, and honestly I'm not even sure how much use you'd have for this stuff at home.
God damn coasties are so fucking stupid. It's a Chicago sandwich shop, they use giardiniera, a Chicago blend of hot peppers and vegetables in an olive oil mix. You certainly don't have to go to potbelly to buy it; they're in every single Chicagoland grocery store, or you can even get it online. And BTW, you can, and should put that shit on everything you love, from sandwiches to pizza and salads or whatever. Every Chicagolander keeps a jar in their fridge for emergencies.
