Mix Nashville Hot Chicken Seasoning with oil and set aside.
Prepare chicken according to package directions.
While chicken cooks, toast buns. Spread both cut halves of each bun with equal parts butter. Place butter side down in a skillet and cook over medium-high heat until lightly browned, about 3 minutes.
Divide cole slaw evenly among the bottoms of each toasted bun. Top each with a chicken filet. Top each filet with equal portions of Nashville Hot Chicken-oil mixture, two pickles and the tops of each bun. Serve.
