Pound chicken breasts until they are about 1/4" thick.
Shake balsamic vinaigrette, brown sugar, and olive oil together in a sealed Ziploc bag. Add chicken and marinade for at least 30 minutes.
Preheat oven to 350 degrees.
Remove chicken from bag and place in a large skillet with olive oil, cook 4-6 minutes on each side (until chicken is a golden brown).
Once browned, remove chicken and place in an oven safe dish. Bake for 10-15 minutes until chicken is cooked through.
In the same skillet used for cooking the chicken, melt butter over medium heat. Add mushrooms and sauté for 2-3 minutes.
Add remaining ingredients and bring to a boil. Reduce heat and simmer for 20-25 minutes, until the sauce has reduced by about 50%.
Top cooked chicken with mozzarella cheese and broil for 3-4 minutes, until the cheese starts to turn golden. Sprinkle with fresh parsley.
Serve chicken immediately with sauce poured over top. We serve it with potatoes and asparagus or green beans, just like the Cheesecake Factory.
