• Step 1: Heat the sesame oil in a large skillet or wok over medium-high heat. Add the chicken and cook, stirring occasionally, until the chicken is cooked through and lightly browned, about 5-7 minutes.
• Step 2: Add the garlic and ginger to the skillet and cook for 1 minute, stirring constantly, until fragrant.
• Step 3: Add the shredded cabbage, sliced bell pepper, and mushrooms to the skillet. Stir-fry the vegetables for 3-5 minutes, or until they are crisp-tender.
• Step 4: Pour in the soy sauce and rice vinegar, and season with salt and black pepper to taste. Toss the ingredients together until everything is well combined and heated through.
• Step 5: Sprinkle the sesame seeds over the top, if using, and serve immediately.
