Preheat the oven to 400 degrees. Line a baking sheet with parchment paper.
Prepare the pickled shallots by combining the sliced shallots with the seasoned rice vinegar in a small bowl and mix well; set aside to allow it time to pickle.
Prepare the chicken by placing it in a small bowl and drizzle some barbecue sauce, to taste, on top; toss to coat the chicken evenly.
Prepare the mini naan pizzas by spooning a small dollop of barbecue sauce in the center of each mini naan and spread it out evenly.
Top each mini naan with some finely shredded cheese then top with a spoonful of barbecue chicken.
Season each mini pizza with a bit of crushed red pepper flakes, sea salt, and freshly cracked pepper, to taste, if desired, and place them on the prepared baking sheet.
Bake the mini naan pizzas by placing the baking sheet into the oven to bake for 7-9 minutes, or until the naan is golden brown and the cheese is gooey.
Remove from the oven and top with some slices of pickled shallot and fresh cilantro and serve immediately. Enjoy.
