Cut the chicken into 1 to 2-inch cubes (or all roughly the same size)
Preheat the oven to 425 degrees F. Line a baking sheet with foil and place a wire rack on top. Spray the rack with nonstick spray.
Season the chicken pieces all over with salt and pepper. Place the pretzels in a food processor and blend until mostly fine crumbs remain. Place the pretzels in a bowl. Stir in the garlic powder.
In another bowl, lightly beat the eggs.
Take each chicken piece and coat it in the beaten egg. Dredge it through the pretzel crumbs, pressing gently so the crumbs adhere. Place the chicken on the rack and repeat with remaining chicken. Once all the chicken is finished, spray it with avocado or olive oil spray.
Bake the chicken for 12 minutes. Flip it gently and spray the other side with the oil spray. Bake for another 10 to 12 minutes.
While the chicken is baking, heat the wing sauce and butter in a saucepan until combined. As soon as the chicken is done, brush the sauce all over the chicken bites. Top with chives and cilantro.
Serve with the cilantro ranch!
