In a bowl, prepare the peanut butter sauce. Add the peanut butter, soy sauce, vinegar, brown sugar and olive oil together to get a nice paste.
In the pan, heat it up with some olive oil and fry the chicken with the ginger and the garlic. Continue until the garlic is cooked.
Add the sauce and stir it around till it is coated all over the place. Add about 1/4 of water and mix. Cover it on low heat for 5 minutes, covered. To keep it saucy, keep adding some water. Add salt and pepper to your liking.
Remove from heat once cooked, add on top of rice and sprinkle some parsley on there.
