Spread Chili Pepper Aioli evenly over each slice of bread, ensuring coast-to-coast coverage over both.
Layer 1st portion of cheese, then Chicken, Peppers, Onions and avocado across the bottom slice of the bread, ensuring each layer of ingredients evenly covers the surface of the sandwich. Season avocado with S&P.
Evenly distribute 2nd portion of cheese over the avocado. Close the sandwich.
Brush melted butter evenly on both sides of the sandwich. Place onto sizzle platter, and into an oven.
Cook until bread is golden brown, cheese is melted and the sandwich is heated through, about 5 minutes. If bread is golden brown and insides are still cool, open up sandwich and place back in oven open faced until heated through.
Cut sandwich in half on a slight bias. Place along the front edge of the plate, with cut sides facing out, as shown in the photo.
