Make the teriyaki sauce first. Combine all ingredients mix well and set aside.
Strain Ty Ling bean sprouts. Clean the mushrooms gently with a paper towel, slice roughly. Peel and julienne the carrots, cut the broccoli into florets. Slice the chicken tenders thin lengthwise. Cut the green onions in thirds.
In a large skillet, heat 2 tablespoon vegetable oil on high heat. Sear the chicken for 3 minutes while stirring, take the chicken out and place it on a plate. In the same skillet add all prepared veggies except the bean sprouts and sear on high heat for 5 minutes, stir constantly. To the seared veggies add bean sprouts, udon noodles and the seared chicken. Pour in teriyaki sauce and let it cook for 5 min on medium heat. The Udon noodles will cook in the sauce and soak up all the liquids.
