I've got a bazillion veggies from the CSA that I really should be eating instead of vegainzing freakin' meat lover's pizzas. Don't worry though, there's some eggplant and zucchini snuck into the sauce, and fried eggplant is great on the pizza, too. Sometimes it's just satisfying to make something inherently meaty totally meatless.
Daiya is a little hard to come by just yet (some of the NYC vegan restaurants like Candle 79 and Blossom are serving it) and I ordered mine online from pangea the vegan store. You can also order it from Cosmo's vegan shop.
