Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the chicken breast into 1-inch cubes and slice the red bell pepper into thin strips.
Place the chicken, broccoli florets, and bell peppers on the prepared sheet pan.
In a small bowl, whisk together the honey, coconut aminos, sesame oil, and minced garlic until well combined.
Drizzle the olive oil, sea salt, and black pepper over the chicken and vegetables, tossing with your hands to coat everything evenly.
Pour half of the honey-garlic sauce over the mixture and toss again, spreading the ingredients out into a single layer.
Roast in the oven for 15 to 18 minutes, or until the chicken is cooked through and the broccoli edges are slightly charred.
Remove from the oven, drizzle the remaining sauce over the hot chicken and veggies, and garnish with sesame seeds before serving.
