Slice the chicken breasts in halves horizontally and pound with mallet until all pieces are the same thickness.
In a bowl, mix the soy sauce, peanut butter, fish sauce, garlic/chilli sauce, olive oil, and juice of 1 lime.
Place chicken pieces in marinade and mix well.
Heat up a large fry pan and fry the chicken pieces with all the marinade on high heat for a few minutes until crunchy.
Transfer the chicken pieces to a clean chopping board and dice into cubes. Then return to the pan with the spring onion and finish cooking on a medium heat.
Garnish with extra lime juice and some fresh spring onion.
