Cover one-half of each breast section with one slice of roasted pepper, one slice of zucchini and a dab of goat cheese. Fold empty chicken breast half flap over the dressed chicken breast half; dust with kosher salt and black and white pepper. Grill to desired temperature.
In 2 tablespoons butter, saute mushrooms and onions until softened. Add Marsala wine and chicken broth; simmer approximately 10 minutes on medium-low heat to reduce.
A little at a time, add remaining 2 tablespoon butter until butter melts and mixture emulsifies. Place chicken in Marsala wine sauce; heat through. Top with tomatoes and fresh parsley. Serve with pasta.
