Whisk together ingredients for the sauce (minus the cornstarch) into a medium-sized bowl.
To a small bowl, add the shrimp and 3 tablespoons of the sauce. Cover, place into the fridge and allow to marinate for approximately 10-15 minutes.
While your shrimp is marinating, you can either steam the broccoli or spiralize the zucchini.
Heat a large, nonstick skillet with sesame oil over medium heat.
Once heated, add the shrimp and allow to cook 3-4 minutes or until shrimp pinks up. Remove from pan, add to a bowl and cover with tented foil to keep warm.
Into the same skillet add the sauce over medium heat. Allow it to come to a light boil. Slowly add the cornstarch 1 teaspoon at a time, whisking continuously to blend. Lower the temperature to a simmer and continue whisking for approximately 1-2 minutes while the sauce continues to thicken.
Raise the temperature to medium-heat, add the zoodles and carrots. Toss with tongs to coat thoroughly. Allow to cook for 5-7 minutes or until the zoodles have softened, but are still tender. Time will be dependent on how firm you want your zoodles. Be cautious not to good too long!
Add in the shrimp, broccoli, and edamame. Stir well to coat.
Garnish with chopped green onions, sesame seeds, a dash of salt and upper, and some red pepper flakes. All optional.
