Place nuts, breadcrumbs, and grill seasoning in a food processor. Pulse grind them until the nuts turn into breadcrumbs. Pour this nutty-breading onto a plate.
In a shallow dish, beat eggs and mix them with half-and-half or milk. Add hot sauce to this mixture.
Spread flour on a plastic board or plate.
Coat both sides of the chicken with flour.
Dip the chicken into the egg mixture and then cover it with the nutty-breading.
Heat a nonstick skillet over medium-high heat. Add vegetable oil to create a thin layer at the bottom of the pan (about 2 or 3 turns of the pan).
Brown the chicken pieces for 2 minutes on each side in the hot oil or until they turn evenly light golden in color.
Transfer the browned chicken to a baking sheet.
Cook the chicken in the oven until the juices run clear and the breasts are cooked through, which should take about 10 to 12 minutes.
