Make the sauce by combining the first four ingredients (and if using powdered seasonings, add garlic and ginger.)
Heat a large skillet or wok over medium-high heat.
Add oil, fresh garlic, and ginger (skip if not using fresh).
Add shrimp sauté for 1-2 minutes.
Add sauce mixture, carrots, and purple cabbage; cook until carrots and cabbage begin to soften, about 2-3 minutes. Garnish with sliced onions, cashews, and sesame seeds, and serve immediately.
