Combine the chutney ingredients in a small saucepan and bring to a boil. Reduce the heat and simmer for 20 minutes.
Prepare the chicken.
Combine the soy sauce, lime juice, curry powder and chicken in a zip lock bag. Shake it to make sure the chicken is coated. Marinate in the fridge for 10 minutes.
Heat a grill pan over medium hight heat. Spray with cooking spray.
Remove the chicken from the marinade and cook about 5 minutes per side or until it reaches 165°F. Remove and let rest for 10 minutes.
Serve with the chutney.
Notes
You can sub peaches, plums or nectarines for the mango. I like to serve this with rice.
