Preheat oven to 425°F. Prepare a sheet pan lined with parchment and dusted with flour. Set aside.
Mix shredded chicken with ¼ cup hoisin (reserve remaining for drizzling), teriyaki and sriracha.
Roll out pizza dough into a 9- x 13-inch rectangle. (It doesn’t have to be a perfect rectangle. Part of the charm of making a flatbread is that it is meant to be rustic.)
Place pizza dough on prepared sheet pan. Using a fork, poke holes throughout, this will aid in achieving a crispy dough. Bake for 10 minutes, until golden brown. Remove from the oven and top pizza dough with shredded chicken . Bake an additional 5 minutes.
To serve top with sliced avocado and greens and drizzle with wasabi sauce.
