Store bought Frozen Chicken Breast inc added water
You can cook it however you like, it's meat. I would suggest slicing it up and stir frying it if you are using a wok. If you want to keep it whole, use a frying pan with a thicker base and place a heavyish lid on top of the breast with a piece of baking paper between the two to even out the thickness of the piece of meat. That will help it to cook more evenly.
