@Keesha You forgot to include the link to the zucchini crust! (LOL - I do that all the time, especially when it comes to email attachments!)
For cheese I use (wait for it) good quality, full fat, real dairy mozzarella. IMHO vegan cheeses available for retail purchase are lower than substandard, especially on pizza. I've tried a bunch of them (daiya included) and have yet to find any that suits my taste. Pizza is one of the very few foods I eat that contains dairy, and I don't eat it very often. Maybe once every 2-3 weeks.
I don't overload pizzas with cheese. The pictured pies are roughly 15" in diameter have about 5-1/2 oz. of cheese per pie. I weigh the cheese to keep from having too heavy a hand with it. Like most foods, good pizza is about balancing quality ingredients: homemade sauce, good cheese, quality toppings and the right amount of spices.
When making pizza I virtually always do a marathon (that particular day I used 20 doughs, yielding 17 pizzas and probably 15 calzones), the aim being to stock my and my daughter's family's freezer for a while. If I'm spending an hour preheating my oven and pizza stones to 550 degrees, and going through the all the dough, sauce and topping steps, I make it worth my while. Plus I really like making pizza!
I have a DIL who is highly sensitive to dairy, plus a son and DIL who are fairly rigid vegans. When they're here for pizza I make them some non-dairy pies.
