In a deep bowl, mix all the ingredients by shaking until they emulsify.
Chop the chicken breasts into cubes and marinate for three hours. After three hours, drain the pieces of chicken from the marinade and push them on the skewers, alternating them with the pineapple and the purple onion squares. Once the skewers are assembled, cook them on the grill or in a pan, making sure that they are well browned on the outside and juicy on the inside. Served with a bed of brown rice and salad.
