Once the sauce comes to a simmer, whisk in the pineapple juice and corn starch slurry.

While the sauce is reducing, heat a few tablespoons on oil in a wide pan and sautee the vegetables until they start to wilt yet maintain their crispness.
½ Cup pruple cabbage, ½ Cup green cabbage, 1 stalk bok choy, ¼ bell pepper
Strain the sauce through a fine mesh strainer to remove the garlic and ginger. Discard the garlic and ginger.
Add the drained and cooled noodles to the sauteed vegetables, tossing to combine.
