Mix all the stuffing mix together and place leave in the fridge to cool
Slice a pocket into the chicken breast – being careful not to cut all the way through
Place a heaped tbsp of the stuffing mix into the breast and fold it over creating a seal
Use toothpicks to keep the seal closed
Season the chicken and sear on frying pan for 1-2 minutes to brown the top
Place in an oven @ 220c and cook for 20 minutes – times will differ depending upon the size of your breasts
With 2 minutes to go on the chicken heat a frying pan with 1 tbsp oil and fry the vegetables for the hash. Remove chicken from oven, allow to rest for a couple minutes while you cook the vegetables.
Remove toothpicks and serve whole or slice at an angle, being gentle not to push down on the breast so you don’t lose the filling
