Few Chicago icons are as revered (or debated) as deep dish pizza. Invented in the 1940s or '50s at Pizzeria Uno by Ike Sewell or Rudy Malnati, the argument rages on, this pie-sized pizza is native to Chicago. Use these seasonings on deep dish or thin crust pies, pasta salads, chicken or eggplant parmigiana, and to make dipping sauce for breadsticks.
