Preheat an oven to 400 degrees. Make the pork rind breading by pulsing pork rinds, mustard powder, and garlic powder in a food processor until it’s all fine and crumbly.
Arrange the breading on a plate and whisk a whole egg in a small bowl. Set these aside for Step 4.
Lay two chicken thighs on a cutting board and pound to about ¼-inch thickness. Season with the salt, pepper, and italian seasoning.
Bread each chicken thigh by first dipping it into the egg, letting the egg run off, and then coating in the pork rind breading. Lay the breaded thighs on a sheet tray lined with parchment paper.
Bake the tray for 40 minutes, no flipping necessary.
While the chicken is baking, make the side dish. In a bowl, toss THAWED broccoli florets with the remaining seasonings and brown mustard. Arrange the broccoli on a well seasoned sheet tray, spread out.
Bake the tray of broccoli in the oven with the chicken for 18 minutes.
Serve each breaded chicken thigh with half the broccoli.
