Prepare the Tempeh Meatballs according to the instructions, but form into 24 small balls as opposed to the 12 larger balls indicated in the original recipe.
While the dough is rising and the meatballs are baking, make the tofu ricotta. Combine all ingredients together in a food process and blend until very smooth and creamy. Add more salt, lemon juice, or nutritional yeast to taste.
Preheat the oven to 500 degrees F if you will be using a pizza stone, or 450 degrees F if you will be using a metal sheet. If you will be using a pizza stone or other stoneware, put it into the oven to preheat now.
Peel and thinly slice the red onion. Wipe the mushrooms clean with a damp cloth and thinly slice those, too. If you do not like mushrooms, you may substitute a thinly sliced red bell pepper.
Once the dough is ready and you have divided it in two and rolled out a round of dough, transfer it to a sheet of parchment paper that fits your pan. Lightly brush the edges of the pizza dough with some extra-virgin olive oil- this helps the crust brown and crisp up as it bakes. Spread 1/2 to 3/4 cup of pizza sauce on it, followed by 12 of the meatballs and half of the onions and mushrooms. Dollop on half of the tofu ricotta (you can also use your desired amount of your favourite vegan cheese, such as cashew cheese, if you do not feel like the tofu ricotta). If you have leftover nut Parmesan from making the tempeh meatballs, you may sprinkle that on top.
Repeat this step with the second round of pizza dough. If you have two pizza stones or pans, you can bake the pizzas at the same time. Transfer each unbaked pizza to a pre-heated stone and bake for 8-10 minutes, or until the edges of the crust are nicely browned and the tofu ricotta has turned golden and appears to have crisped up.
While the pizza is baking, make the Green Goddess Ranch dip. Combine all ingredients in a high speed blender and blend until smooth.
Remove the pizza from the oven and allow it to rest for 5 minutes before slicing and serving with a generous amount of Green Goddess Ranch Dip (that stuff is addictive!). And beer. Don't forget the craft beer.
I own two Pampered Chef stoneware cookie sheets, which I bake pizza on. I highly recommend investing in some- they are made with non-toxic American clay; don't contain any nasty Teflon or other non-stick chemicals; and are truly timeless.
Prep and cook times do not take into consideration time to make meatballs and pizza dough.
