Slice the roll lengthwise and remove a small amount of excess bread from the center with your fingers. Set aside. Place the chicken on a flat top griddle
with the oil and cook until golden. Top the meat with some Buffalo sauce and cover with the provolone. Place the opened sub roll over the chicken and cheese and steam the bread for 1 minute. Scrape the chicken and cheese into the roll and top with some sauteed
onions. Cover with more Buffalo sauce
, and then drizzle
with blue cheese
dressing. Slice the sub in half and serve.
