Preheat oven to 375 degrees.
Lightly spray a large baking sheet with non-stick cooking spray and set aside.
In a large bowl, mix together the ground chicken, bread crumbs, eggs, jalapenos, mangoes, cilantro, coconut milk, salt, pepper, chili powder, garlic powder, and cumin until thoroughly combined.
Shape into balls that are about 1 1/2 inches in size (should make about 35-40 meatballs).
Set each meatball on the prepared baking sheet.
Cook for 20-25 minutes or until meat is cooked through.
While the meatballs are cooking, make the coconut mango sauce.
Combine all the ingredients for the sauce in food processor or blender.
Pour the mixture into a saucepan. Bring to a boil, then remove from heat.
Serve sauce with the meatballs.
