Preheat oven to 425°F. Cut up the pineapple, mango and limes and set aside. Mix together the kosher salt, coriander, cumin, cinnamon, white pepper and cayenne in a small bowl.
Either use or cut the whole chicken in half or spatchcock (See Note and watch video).
Rub chicken with spice mixture all over, pressing to adhere.
Heat the oil in a large ovenproof skillet over medium-high. Cook chicken, breast side down, until browned and beginning to crisp, about 5 minutes.
Transfer chicken to a roasting pan with pineapple arranged on bottom in pan. Place chicken, skin side up, on top, then add mango and lime pieces all around. Transfer to oven and roast uncovered until an instant-read thermometer inserted into the thickest part of thigh registers 165°F, about 40–45 minutes.
While chicken roasts, make glaze. In a small saucepan over medium heat bring pineapple juice, vinegar, garlic, brown sugar, paprika and serrano chiles to a boil and cook until thickened, 12 minutes.
In last 5 minutes of roasting chicken, brush with the glaze and roast until glaze is bubbling.
Transfer chicken to a cutting board and allow to rest 10 minutes. Serve chicken, roasted pineapple and mango (discard limes) with any juices from skillet on top.

Notes
The whole chicken can be halved or spatchcocked. By flattening out the chicken, you're exposing the legs to a higher heat, helping them cook faster than the breasts which results in a juicy meat. It also ensures crisper skin and is much faster to cook than traditional whole roasting.
If spatchcocking: be sure to have the chicken on a clean cutting surface breast side down.
Starting at either the tail end or the neck area, use sharp kitchen scissors or poultry shears, and cut along each side of the backbone (cutting through the rib bones) as you go towards the other end and remove the backbone.Discard the backbone or freeze for soup stock.
Flip the chicken over and press down hard OR, after removing the back bone, spread the chicken out and turn over. Flatten the breastbone using the heel of your hand so that the meat is butterflied and all one thickness.
Spatchcock Tip: If it doesn't lay flat do this - In the center area near the neck there will be a triangle of cartilage right where the breastbone starts (see my finger pointing to it in the photo below). Using a sharp knife, cut down a quarter inch and spread the cut area open to reveal the breast bone.
