It's easy to make vegan too, if you make a "ricotta" out of tofu. Thoroughly wash your hands, and then squish the tofu between your fingers and doing that until it's basically ricotta texture. Add salt, nutritional yeast (NOT bakers yeast), oregano, and basil. Use that instead of normal cheese.

It'll be ricotta-like. If you want something cheesier that's still vegan, I recommend Daiya as a faux-cheese brand.
