I have honestly made this so many times now that I cannot begin to guess a number. I will tell you this: when I am baking ANYthing now that resembles dough ... my kids will say: "You aren't making pizza AGAIN, are you?!"
They loved it but after a few weeks... they started tiring. I did not. I have made these with thinly sliced yellow squash and zucchini straight from the garden, with portabello mushrooms, with sun dried tomatoes, broccoli, chicken, baby spinach leaves, red onion, Vidalia onion, and the list keeps going on and on and on and on.
I shared the link at the bottom of the site I got it from. No surprise ... another one from The Kitchn!
