Quinoa can be used to prepare wonderful gluten-free pizza crusts. This quinoa crust pizza recipe is in the deep dish style, with lots of fresh veggies. For a richer pizza, you can also add some of the store-bought vegan cheese that is closer to the standard non-vegan pizza. Many of the new non-dairy cheese are very stretchy and gooey, very similar to regular cheeses. However, be sure to choose those without casein (a milk protein) and carrageenan (an unhealthy additive).
