Using a serrated knife, split hoagie bun 3/4 of the way through; press open on a baking sheet. Spread both sides of the roll with desired amount of dressing. Top with chicken, Sautéed Kale and cheese. Place baking sheet 6-10" from preheated broiler; cook until cheese melts and edges of the roll start to turn golden-brown and toasty (1-2 min.). Remove from oven, sprinkle with red pepper flakes, close sandwich and cut in half on the diagonal with a serrated knife.
