Make sure the liner is in your Instant Pot, then press the SAUTE button. Once hot add both the sausage and the onion to the pot. Cook, stirring often and crumbling, until almost browned throughout.
1 lb mild pork sausage, 1 small yellow onion
Add the ginger and garlic to the pot, stirring to combine, and cook for 30 seconds- stirring constantly.
1 1/2 tbsp ginger paste, 2 tbsp minced garlic
Add soy sauce, vinegar, oil, and broth to the pot. Using a sturdy wooden spoon, stir and scrape up any stuck on browned bits to deglaze the bottom of the pot. Hit the CANCEL button.
4 tbsp soy sauce, 3 tsp seasoned rice wine vinegar, 2 tbsp sesame oil, 1/4 cup chicken broth
Add the coleslaw to the pot, but do not stir. Close the lid, and set the vent valve to the sealed position. Cook on HIGH pressure for ZERO minutes.
1 14 oz bag coleslaw mix
As soon as it's done cooking, carefully open the vent valve to perform an immediate quick release of the pressurized steam.
When safe to do so, stir the mixture and serve warm over a bed of steamed white rice.
Garnish with the sliced green onions and Sriracha, as desired.
