Whisk all sauce ingredients together in a bowl and set aside to let the flavors mix.
In a large skillet, heat 3 tablespoons of oil until very very hot (almost smoking) and saute shrimp until pink on both sides – roughly 3 to 4 minutes. Remove to a plate, cover, and set aside.
Add the remaining 3 tablespoons of oil to the skillet and place the broccoli and snow peas in and stir to coat in the oil. Add the 1/4 cup of water and cover with a lid for a few minutes – until the broccoli has turned a nice bright light-green.
Remove the lid and add the bamboo shoots, baby corn, and water chestnuts. Saute until they are heated through. Add the shrimp and any juices that have accumulated in the plate.
Pour on the sauce and toss to coat. Serve over rice with roasted cashews.
