Brine the chicken: Up to 12 hours prior to cooking the chicken, whisk the buttermilk, salt, and hot sauce or sriracha in a large bowl. Place the chicken into the buttermilk brine. Cover and refrigerate
Pour about an inch of oil into a 10-inch skillet and preheat over medium-high. Whisk together the flour, salt, onion and garlic powder, cayenne pepper, and black pepper together in a bowl
Remove chicken from the brine and dip into the flour on both sides, then dip back into the buttermilk and back into the flour. Fry on each side for about five minutes, until golden. Remove to a plate lined with paper towels
To serve, place each piece of chicken on a waffle and top with Wicked Pickle Chips and lettuce and tomato if desired
