In a large serving bowl, mix the lettuce, tomatoes, purple cabbage, carrots, red onion, cilantro, and half the blue cheese crumbles. Cover and refrigerate while you prepare the chicken.
Whisk the egg in a small shallow bowl and in another shallow bowl, add the flour, cornstarch, salt, pepper, onion powder garlic powder, and paprika.
Dip the chicken tenders in the flour, then in the egg, and then once again in the flour.
Heat a large skillet (I like to use my dutch oven to keep the oil from splattering) over medium-high heat. Once sizzling hot, place the chicken tenders in the pan for about 3 minutes on each side or until golden brown. Use rubber tipped tongs to carefully turn the chicken so you don't lose the breading. Place the chicken on a paper towel lined plate to cool.
While the chicken cools, whisk together the buffalo sauce, melted butter, and honey. Dip each piece of chicken in the sauce to coat and cut into 1 inch pieces. Drizzle any leftover sauce over top of the chicken.
Toss the salad with the dressing, place chicken, avocado, and remaining blue cheese crumbles over top. Drizzle with remaining honey buffalo sauce and dressing if desired.
