Cut king oyster mushrooms and chicken breast into bite-sized pieces.
Slice garlic thinly.
Add olive oil to a pan and sauté garlic over medium-low heat.
When the garlic fragrance rises, add chicken breast and cook thoroughly.
Once the chicken is cooked, add king oyster mushrooms and salt, and stir-fry.
Add parsley and pepper, stir-fry once more, and finish.
