Spray skillet with non stick cooking spray and heat on medium high.

Pound chicken to 3/8" thickness. Season on both sides with pepper and place in pan.

Cook until brown, about 4 minutes, then flip. Cook an additional 4 minutes.

Meanwhile, whisk together remaining ingredients. When chicken is brown on both sides, pour the sauce over chicken.

Bring to a boil. Reduce heat and simmer 5 minutes, or until chicken is tender and cooked through and sauce is reduced.
