Step 1

Stir together the ingredients for the stir-fry sauce and set aside. Taste and adjust seasoning if needed.

Step 2

Heat the oil in a large skillet or work over medium-high heat. Once the oil is hot, add the chicken in a single layer. Season with black or white pepper. Cook until just cooked through and browned, about 3-4 minutes. Remove the chicken using a slotted spoon. Set aside.

Step 3

If needed, add an extra drizzle of oil to the pan. Add the onion, broccoli, mushrooms, red bell pepper, and carrot to the pan. Cook for 4-5 minutes until the vegetables are tender-crisp.

Step 4

Add the chicken back to the pan along with the stir-fry sauce. Cook for 1-2 minutes until the sauce thickens.
