Combine all ingredients in a resealable bag or airtight container. Shake very well, until chicken is coated in the marinade.
Marinate in the fridge for at least 1 hour and up to 2 days in advance.
When ready to serve, cook the chicken over medium high heat in a skillet with olive oil. Sear for 3-4 minutes on each side, then reduce heat to medium low to cook for 10-12 minutes, until fully cooked.
(Optional) Slice the chicken into bite-sized pieces and toss back in the pan with a drizzle of olive oil to get crispy on all sides.
For the Cilantro Lime Rice:
Stir the lime juice, chopped cilantro, and salt in the cooked rice. Set aside.
For the Mango Salsa:
Toss all ingredients together in a mixing bowl. Season with salt and black pepper to taste. Serve with the cooked chicken and cilantro-lime rice to be enjoyed!
