The kebabs use lean white meat chicken breast and a combination of antioxidant-rich red bell pepper, peach and ataulfo mango. Ataulfo mangoes (sometimes labeled as champagne mangoes in the grocery store) are similar to other mango varieties but tend to be sweeter, juicier and less fibrous. They are small and have golden yellow skin. The red bell pepper provides Vitamin C and lycopene, a phytochemical that has been said to benefit heart health and reduce risk for prostate cancer. Plus, it adds a crunchy sweetness that works well against the juicy fruit. The red onion contains anthocyanidins, which may promote blood vessel health, and provides an additional flavor boost when nestled against the chicken chunks.
