Heat the sesame oil in a large pan.
Add the chicken and cook 4-5 minutes per side or until it starts to brown.
Add the broccoli florets, sliced peppers, and carrot sticks. Cover and cook over medium heat till the broccoli begins to get tender, stirring frequently.
In a small bowl, whisk the teriyaki coconut aminos with the arrowroot powder.
Pour the sauce into the pan and toss to coat the chicken and vegetables well.
Add the sliced water chestnuts to the pan and stir in.
Simmer for 5 minutes or until the sauce begins to thicken.
Garnish with sesame seeds.
Enjoy!
