Preheat the oven to 425 degrees F.
Whisk the dressing ingredients together and set aside.
Slice the chicken breasts in half horizontally, but not all the way through, opening like a book.
Add about 1 tablespoon of dressing to each open book chicken breast.
Lay a slice of cheese, salami, prosciutto, banana peppers and roasted peppers to each. Top with another slice of cheese and fold over, closing the stuffing inside the two pieces of breast.
Tie together to hold it's filling and place in a 9 by 13 dish.
Pour remaining dressing over the chicken and bake 30 minutes or until the chicken is no longer pink when sliced or an internal thermometer reads 165 degrees F.
Enjoy immediately!
