In a large skillet over medium high heat, add the sesame oil and chicken.
Cook for about 5 minutes until mostly cooked through.
While that is cooking, in a small bowl, combine orange zest and juice, coconut aminos, ginger, tomato paste, honey, red pepper, and garlic powder. Stir as best you can with a spoon.
Pour over chicken and stir to evenly coat.
Cook for 5-10 minutes or until chicken is fully cooked through.
Add tapioca starch if you want the sauce thicker. Stir it in and cook for a couple minutes for it to thicken.
Serve over cauliflower rice.
Notes
*For Low FODMAP: leave out honey and tomato paste and use 1 tablespoon garlic oil in place of the garlic powder
