Cut chicken into cube-sized shapes, and trim fat.

Heat pan with any kind of oil (i chose olive oil), do the water test to check if it's hot enough. Carefully place chicken in pan, careful not to get burnt.

Pour in 1/2cup sweet and sour sauce, garlic, garlic salt and soy sauce. Toss chicken in mixture to coat it evenly.

Check to make sure chicken is thoroughly cooked before tossing one last time.
