Combine first 7 ingredients in a bowl; stir well with a whisk.
Sprinkle chicken with salt and pepper. Heat a large nonstick skillet coated with cooking spray over medium-high heat until hot. Add chicken; cook 3 minutes on each side or until browned. Remove chicken from pan. Add mango mixture; bring to a boil. Return chicken to pan; reduce heat, and simmer 15 minutes or until chicken is done and sauce thickens, stirring occasionally.
This is very good. Quick and easy to make, too. I've made it several times, just as written.
