What are some good toppings to put on an allergy free pizza?

I just bought Bob's Red Mill Gluten Free pizza crust. I can eat pepperoni and (lactose free vegan cheese) but I was wondering how do I make a spinach and vegan cheese pizza. Kind of of spinach do I use? Or what is the best vegan cheese to put on pizza. Im so excited I can make my own pizza lol. Any new allergy free ideas will be greatly appreciated. (I cant have ham right now, Im pregnant)
