Cook the brown rice according to package instructions or use pre-cooked rice and set aside.
In a small bowl, whisk together the coconut aminos, rice vinegar, honey, and arrowroot powder to create the sauce slurry.
Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the sesame oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5 to 7 minutes, then remove from the pan.
In the same pan, add the minced garlic, grated ginger root, and red pepper flakes, sautéing for 30 seconds until fragrant.
Toss in the broccoli florets and sliced red bell pepper with a tablespoon of water, then cover the pan to steam for 3 minutes until tender-crisp.
Return the cooked chicken to the skillet and pour the sauce mixture over the ingredients.
Stir constantly for 1 minute until the glaze thickens and becomes glossy, coating the chicken and vegetables.
Serve the mixture immediately over the warm bed of fluffy brown rice.
