I've been purchasing the undressed cornmeal crusts from
Vicolo (Whole Foods) for a couple months and these are the best store bought crusts I have ever had. You can make them cheaper, but they are price reasonable so they come in handy when you need a quick delicious crust.
Today I'm lucky enough to be working on a stage that has a small kitchen and I prepared 6 pies using this crust. They were gobbled up in minutes by the crew. Very tasty and very hearty, with no prep time or mess for the dough! Try it out.
