No two Chicagoans will tell you exactly the same thing about deep-dish pizza, but these are the basics – three layers of dough, spicy sausage filling, topped with sauce and cheese. Great hot or cold. If you want to speed this up, omit the spinach (and/or if you aren't keen on spinach) and used doctored-up jarred marinara sauce. This is a very hunky pizza - making it perfect for the beach picnic (cold) or on the deck at night, or brown-bagging.
