I wanted pizza, but I was short on Daiya shredded cheese substitutes. I am also not entirely satisfied with the melting properties if thay fake cheese. Specifically, it's the lack of melting. It's just not right. I did have some sliced "provalone" though, and the seven slices remaining were perfect for making a 3x3 grid with halves in the corners.
Verdict: the "cheese" coverage is better, and the slices make up for some of the missing sheet-of-melty-cheese texture properly decadent pizza needs. I think I will try this more often.
