I have tried allergy free pizza with Nathan a couple of times but he wouldn't really touch it. Mostly frozen and already prepared. Today, I took his bread, toasted it, put pizza sauce and then used a Vegan mozzarella cheese, a slice of pepperoni and broiled it so the cheese melted. He really did like it!! He gets so excited about pizza and has always seen us eating it so I am happy that we have a pizza for him.
