Remove the dough from the package and let rest, about 20 minutes while you prepare the rest of the ingredients.
Heat a non-stick skillet to medium-high heat and add 1 tsp. oil.
Add the onions, reduce heat to medium-low and cook, stirring often until onions have caramelized.
In a high-powered blender, place in the drained cashews, nutritional yeast, salt, garlic, cornstarch milk and lemon juice. Blend, on high until smooth and creamy, about 4-5 minutes. The sauce should be very smooth, not grainy.
Lightly flour your hands and stretch the dough out onto a pizza stone or peel. Brush the crust with the remaining 1 tsp. of olive oil and place in the oven for 10-12 minutes until golden brown. (If you are using another brand of pizza dough, make sure to cook according to package directions).
Remove the dough from the oven and let cool slightly.
Add the garlic-cashew cream in a single layer.
Top with caramelized onions, fresh chop herbs, red pepper flakes and Parmesan cheese.
