Dredge the chicken in breadcrumbs. Heat oil in a large skillet over medium-high heat until hot. Add the chicken, and cook for 2 minutes on each side or until browned.
Add the broth mixture and mushroom slices to the skillet, and bring to a boil. Cover, reduce heat, and simmer for 20 minutes or until the chicken is done. Remove chicken from the skillet with a slotted spoon; set aside, and keep warm.
Bring broth mixture to a boil. Cook for 4 minutes or until reduced to 1 cup. Spoon the sauce over chicken. Garnish with fresh parsley, if desired.
