Place crushed Chex and seasoning in a bowl; combine.
Whisk the eggs in a bowl.
Dip each chicken thigh in the crumbs, then the egg mixture then back in the crumbs to fully coat.
Place chicken thighs on a baking sheet.
Drizzle the melted margarine over the top of the chicken thighs, coating each as much as you can.
Place in the fridge for half a hour.
Bake for 35-40 minutes at 375 degrees Fahrenheit until the chicken reaches a temperature of 185. (chicken thighs are better when cooked slightly longer!)
