Preheat oven to 450°F (212°C).
Add vegan cream cheese and water into a microwave safe bowl. Microwave for 30 to 45 seconds for vegan cream cheese to start melting. Mix together until smooth and creamy, you may need to microwave another 15 to 25 seconds.
Finish preparing the sauce by adding in half of the chopped spinach, chopped garlic, and lemon juice. Mix together. If you are using salt and pepper you can add in a dash to this as well and add more to your taste. You can taste this as everything is cooked or a vegetable. Set it to the side.
Using a sharp knife begin to thinly slice your potatoes. The thinner you can cut them the better and if you have pieces that don't come out in full circles that is okay you can still layer them. Set the slices to the side.
Spread the dough onto a baking sheet or pizza pan if you have one. If using oil add about a tablespoon of oil to the pan and roll the dough in it to help you spread it out. If using flour do the same. Spread the dough out to be as a thin and big as you want it to be. I opted for a circle pizza but you can make it square if you want.
Bake in the oven for 5 minutes to help the crust start to cook.
Remove from oven and add the chopped spinach that didn't go into the sauce on top of the dough. You can save a little for garnish. Then add the sauce on top and spread it out. I didn't add all the spinach because I was worried it would over power the sauce and just preferred to do it this way. Once the sauce is spread out start to layer the potatoes so they slightly overlap each other until all potatoes are added.
If using oil you can drizzle 2 tablespoons of oil overtop the potatoes, if not skip this step. Then add some salt and pepper on top if you like.
9.Bake for 20 to 25 more minutes or until the potatoes are cooked and crispy.
When done let the pizza sit for at least 10 minutes. Cut into 8 pieces (or more if you like) and enjoy.
