Marinate the Chicken: In a bowl, combine the cubed chicken with soy sauce, sherry, sweetener, and starch. Mix well and let it rest for about 15 minutes.
Cook the Chicken: Heat 1 tbsp of avocado oil in a skillet over medium-high heat. Add the marinated chicken and cook until it’s browned and fully cooked. Remove from the skillet and set aside.
Prepare the Sauce: In a separate bowl, whisk together chicken broth, starch, soy sauce, sweetener, sherry, and white vinegar. Set aside for later use.
Stir-Fry the Vegetables: In the same skillet, add another tbsp of oil. Toss in the red bell pepper and sugar snap peas, cooking for about 2-3 minutes until slightly tender.
Add Aromatics: Stir in the minced garlic and grated ginger, cooking for about 30 seconds until fragrant.
Combine Ingredients: Return the cooked chicken to the pan and mix everything together.
Thicken the Sauce: Pour in the prepared stir-fry sauce and stir everything together. Let it simmer until the sauce thickens. If using, add peanuts at this stage.
Final Touches: Garnish with green onions and serve warm.
