Heat the vegetable oil and toasted sesame oil in a large skillet over medium-high heat. Add the onion and mushroom and cook 2 minutes, stirring occasionally.
Add the chicken, garlic, and ginger, and cook until the chicken is browned, about 5 to 7 minutes, stirring occasionally.
Turn down the heat to medium. Add the hoisin sauce, soy sauce, vinegar, cornstarch slurry, chili garlic sauce, black pepper, salt, and water chestnuts.
Cook until the sauce is thickened, about 2 minutes, stirring frequently.
