Dice mango, cucumber, and pepper. Slice onion and minced basil. Add all ingredients to a bowl and season with salt, pepper, lime juice and olive oil. Mix well and set aside.
Cook white rice, spoon the mango salad over the rice and pour the dressing over everything so the rice absorbs the flavors.
Heat your BBQ to 400℉, cook chicken on both sides until internal temperature is 170-175℉, this takes about 20-25 mins. The spices are dark, so don't worry if the chicken looks very dark, it's not burned.
Top with chopped scallions and a squeeze of lime and enjoy!
