The almond based mozzarella substitute is pretty good. Have you tried using the Bob's Red Mill Gluten-Free Pizza Crust mix? It is very strange in dough form, but makes a tolerable crust substitute when the directions on the package are followed.
Also, are you interested in a possible potluck or picnic inland northwest steemit meetup in late September some sunday afternoon? Perhaps at Farragut State Park?
