Cut chicken up into 1 inch cubes and cook in sesame oil and avocado oil. Cook on medium to high heat for about 5 minutes until nearly cooked through. Set aside on a cool burner.
While the chicken cooks, mix in a bowl: xanthan gum and water- stir and set slurry to the side.
In another small saucepan add the brown sugar, coconut aminos, barbecue sauce, Chinese 5 spice, ginger and lime juice and combine on low to medium heat on a gentle simmer for 2 minutes.
Add the slurry to the small saucepan and mix together with a whisk for 3 – 4 minutes or until thickened.
Add broccoli to the pan with the chicken and pour your sauce over and cook for 5-8 more minutes on medium heat.
Garnish with sesame seeds and serve.
