Add all pineapple salsa ingredients to bowl. Mix and cover. Then set in refrigerator until time for use. Make sure to do this first. The longer the ingredients hang out, the better the flavors will come together. It's best to do this the night before serving, but you don't have to.
Chop chicken into small bite-size pieces. Set aside
Mix spices for chicken. Set aside.
Heat 2 tablespoons of olive oil in a skillet over medium heat. Then add chicken and spice mix. Stir until chicken is evenly coated with spices.
Stir often to ensure that the chicken doesn't stick to the pan and the chicken pieces don't stick together. Cook chicken for 6-10 minutes.
When chicken is just fully cooked, squeeze the juice from half a lime over the chicken, then turn off the heat and cover for 10 minutes.
