This recipe was developed after trying different Veggie pizzas at various potlucks and me running short on time. It's a good thing the people I work with are good guinea pigs. Prep time varies depending on how much hands on chopping vs my new friend the salad shooter for the grating. Recipe can be easily halved. Just use a 9x13 pan instead of the jelly roll pan.
You can use either prepared ranch dip or grab a 16 ounce container of sour cream and a packet of ranch dip mix.
