It is made with a vegan cheese that melts and tastes good the brand is Daiya.
These cost a little over a dollar for one, but you can easily make them at home.
You can also have them make you a pizza with rice crust and vegan cheese.
I'm so excited to have a healthy pizza place I can recommend. I have not tried it yet, but I plan on going soon.
They are a good choice for pizza because they ferment the dough for 3 days and every thing is locally grown organic :)
