Once all veggies are added, season with chinese five spice, ginger and garlic.
Pour ¼ cup of the sauce into the sauté pan with the veggies and let it come to a low bubble until it starts to thicken.
Add the Shrimp and toss to coat. Add more sauce if needed. Allow to thicken.
Add the cooked pasta, toss with tongs to coat. Then add the chopped green onions and toss it all together.
