Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with olive oil, half of the salt, and half of the pepper on the prepared sheet.
Roast the vegetables for 15-18 minutes until they are tender and show slight charred edges.
While the vegetables roast, dice the chicken breast into bite-sized pieces and toss in a bowl with arrowroot powder and the remaining salt and pepper.
In a small ramekin, whisk together the coconut aminos, honey, minced ginger, and minced garlic to create the teriyaki glaze.
Heat a non-stick skillet over medium-high heat with the toasted sesame oil.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through.
Pour the teriyaki glaze into the skillet with the chicken, stirring constantly for 1-2 minutes until the sauce thickens into a glossy coating.
Divide the roasted vegetables onto plates, top with the crispy glazed chicken, and garnish with sesame seeds.
