For an extra layer of flavor, consider adding a drizzle of your favorite barbecue sauce over the pulled pork before topping with cheese. Pickled jalapeños, a dollop of sour cream, or a sprinkle of fresh cilantro make excellent additions to these nachos. Feel free to adjust the amount of Sriracha to suit your spice preference. For a milder slaw, start with half the amount and add more to taste.
