Vegan Spinach Alfredo Pizza

1 Make the Alfredo sauce. In a small sauce pan, or skillet. Heat the vegan butter on medium high. Melt and then add the flour. Whisk together to make a paste(roux). 
2 Now, add the non dairy milk to the pan and whisk to combine the milk with the roux. Whisk until fully combined. Then add the nutritional yeast, lemon juice and a pinch of salt and pepper. 
3 Bring to a simmer, reducing heat as needed. Whisk until the sauce becomes thick and creamy. It should only take a few minutes. Add another pinch of salt and pepper if needed. Remove from heat. 
4 Preheat the oven to 450 degrees. 
5 Now, squeeze as much liquid out of the thawed spinach as you can. 
6 Then roll your pizza dough out as thick as you want. I like mine really thin and crispy, so I like to press mine out into a large sheet pan. Place on a baking sheet or pizza pan that is oiled or sprayed with non stick spray. 
7 Next, spread the vegan Alfredo sauce over the whole pizza. Then sprinkle with chopped garlic and then sprinkle with the spinach. Top with the vegan cheese. 
8 Bake at 450 degrees for about 15 minutes or until the dough is crispy and brown. Serve! I love red pepper flakes and agave drizzled on top.
