1. Prepare the sweet-spicy bang bang sauce by whisking together mayonnaise, sweet chili sauce, honey, and Frank’s RedHot Sauce until smooth. Set aside in the fridge.
2. Make the buttermilk batter by combining buttermilk, flour, cornstarch, egg, hot sauce, salt, and pepper in a bowl. Whisk until smooth.
3. Spread Panko breadcrumbs on a shallow plate and pat the chicken dry. Dredge each piece in the buttermilk mixture, then coat with Panko.
4. Heat oil in a Dutch oven to 360°F (182°C). Use a thermometer or test with a piece of panko to check readiness.
5. Fry chicken in small batches for 2–3 minutes until golden and crispy. Drain on paper towels and sprinkle with salt.
6. Serve immediately over a bed of vegetables, drizzled with the bang bang sauce or served on the side. Garnish with parsley.
