I'd call this as french style of pizza because it's thin and crispy. I've made this with puff pastry of "Marie" french product. I really love this ready made pastry sheet because it's thin and delicate yet crispy.
I lightly spread tomato sauce on the bottom then arranged slices of mushroom, ham and cheese. I should have pre cooked mushrooms because they're watery. It became thin crust ed pizza like pie.
