Easy but yummy chicken recipe

Found an easy chicken recipe that uses only 7 ingredients. So easy and inexpensive to make. If I can cook it, so can you! 2 cups thinly sliced onions 1/2 cup olive oil or cooking oil 1 chicken, cut into serving pieces 1 1/2 cups chicken stock 2 tbsp soy sauce 3-5 potatoes, peeled and cut into quarters 1/4 cup vinegar
