I made it exactly and they were delicious. It wasn't clear about the pizza dough, so I bought pre rolled dough and cut out rounds with a cookie cutter. Which worked fine but didn't puff up like the photo.
I made this for a finger food only gathering and people I didn't even know sought me out to tell me they could not stop eating them. I followed the recipe as written with the exception of the red pepper flakes which I replaced with a couple of fresh basil leaves. It took me about 30 minutes to prepare all 32 pizzas.
