Step 1

In a medium size bowl, combine the ingredients for the marinade and add in the thinly sliced chicken breast. I recommend letting this marinate in the fridge for at least 30 minutes to overnight. Otherwise, let this sit while you prep the other ingredients.

Step 2

Combine all the ingredients for the sauce in a small bowl and set it aside.

Step 3

Heat a wok or pan over high heat. Wait until the pan is hot and then add the vegetable oil and lay the chicken pieces flat in a single layer - leave out the marinade. In order to get a good sear, don't crowd the pan and leave the chicken pieces alone until you get a golden brown sear, anywhere from 30 seconds to 1 minute. Flip over the chicken and repeat. Remove the chicken from the pan.

Step 4

Add the mushrooms and zucchini to the pan and saute for 2 - 3 minutes. Lower the heat to medium and add the chicken back in.

Step 5

Next add in the sauce - use about half if you prefer less sauce(stir the sauce before adding it as the cornstarch will settle). Saute everything together for 1 - 2 minutes until the sauce has thickened. Top with sesame seeds. Serve immediately.
