Cut chicken, potatoes, carrots, and onions into bite-sized pieces.
Stir-fry the chicken and vegetables in a pan.
Make a seasoning sauce with soy sauce, sugar, minced garlic, and pepper.
Pour the sauce and water over the ingredients in the pan and bring to a boil.
Once all ingredients are cooked, add the cup noodles and cook further.
When the cup noodles are done and the sauce has thickened, it's ready to serve.
