MAKE THE FRIED CHICKEN
In a bowl, add the milk, pickle juice, chili powder, salt, dried mustard powder, garlic powder, smoked paprika, black pepper, onion powder, and oregano. Whisk together.
In another bowl, add flour, cornstarch, mustard powder, chili powder, salt, garlic powder, smoked paprika, black pepper, onion powder, and oregano. Whisk and set aside.
Add 4 tablespoons of the wet batter into the dry and mix around to create a flaky texture.
Dip each piece of chicken into the wet and allow the excess to drip off. Then transfer to dry and use the other hand to bread the chicken. Pat it well and shake off any excess flour. Transfer to a plate to rest for 10 minutes after breading all the chicken.
Heat oil to about 350°F in a frying pan. Drop a few pieces in at a time, making sure not to overcrowd them. Fry in 2 batches if needed. Fry until golden brown all around, about 7-8 minutes. Make sure to rotate them around as needed for even browning but don't bother them too much. Transfer to a wire rack to let any excess oil drip off.
ASSEMBLY
Add two Hawaiian Sweet Rolls at a time to the preheated waffle maker on the low heat setting. Cook for 1 to 2 minutes until golden and crispy. Repeat with the rest of the rolls.
In a bowl, combine honey, hot sauce, melted butter, and red pepper flakes to make the hot honey sauce.
Add the fried chicken and toss in the sauce.
Add pickles and fried chicken to each waffle to turn them into waffle sliders and enjoy!
