Mix together beef stock, soy sauce, erythritol, garlic, sesame oil, rice vinegar, ginger, sriracha, onion powder & white pepper.
Put diced beef into pressure cooker, add in your sauce mixture and stir until combined.
Cook on high pressure, 15 minutes, quick release.
Remove beef from mixture & set aside.
Turn on saute mode, mix in xantham gum until desired thickness (Should coat a spoon).
Add beef back to sauce.
Garnish with spring onion & sesame seeds.
Serve with rice or rice alternative (I used egg fried barenaked rice).
