Prepare all ingredients by slicing the chicken and vegetables.
Heat sesame oil in a large frying pan or wok over medium-high heat.
Add minced garlic and ginger, sautéing until fragrant.
Increase the heat to high and add the sliced chicken, cooking until browned.
Season the chicken with salt and pepper while it cooks.
Add bell pepper, broccoli, and carrot to the pan.
Stir-fry the vegetables until they are tender yet crisp.
Pour in soy sauce and mix well to coat the chicken and vegetables.
Cook for an additional 2-3 minutes until everything is heated through.
Remove from heat and sprinkle sesame seeds on top before serving.
