Preheat the oven to 180C or 355F.
Mix chickpea flour, water, olive oil, salt, pepper, and turmeric. Stir well until you get a smooth mixture. Unlike a regular pizza dough, the chickpea crust will be a rather liquid, yet a slightly firm, pourable mixture. Add a little bit more water if too dry or more chickpea flour f too wet.
With a spoon or spatula, evenly spread the mixture on baking paper or silicone baking mat in a 1/2 cm to 1cm (1/4 to 1/2 inch) thick layer. Sprinkle a bit of olive oil on the baking paper or silicone mat before you spread on the dough to avoid it to stick to the paper or mat.
Bake the crust into the oven for about 15 min until the edges are very lightly golden. Do not overbake!
Meanwhile, make the cashew cheese. Blend all ingredients in a blender and set aside.
Remove the crust from the oven. Spread it with the (homemade) tomato sauce and add the cashew cheese on top of the tomato sauce layer.
Top with your favorite veggies and put the pizza back into the oven. Bake for 10-15 minutes. Or until the veggies are cooked.
