Add the chicken, hot sauce, and butter to a large saucepan over medium-high heat. Bring to a boil, then lower heat, cover and simmer for 15 minutes or until chicken is cooked through.
Heat the butter in a large saute pan over medium heat. Add the onions and saute for 13 minutes, until soft.
Stir in the sugar and saute for another 10 minutes or until onions are caramelized. Set aside and preheat the panini griddle.
Assemble the sandwiches as follows: Spray the bottom of the bread with butter spray and set it on the grill. Add in layers evenly with the onions, blue cheese, and chicken. Spoon some of the cooking sauce over the chicken, cheese, and onions for more buffalo flavor.
Top with the mozzarella cheese and cover with the top of the bun. Spray the top bun with butter spray and close panini press. Grill for 5 minutes until cheese is melted and bread is toasted.
