Pat the chicken breast dry with a paper towel and cut into bite-sized cubes, then season evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the honey, tamari, minced garlic, and grated fresh ginger until well combined.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the chicken cubes to the skillet in a single layer and sear for 4-5 minutes, turning occasionally until golden brown and cooked through.
Toss the diced red bell peppers into the skillet with the chicken and sauté for an additional 2 minutes until tender-crisp.
Pour the honey-garlic sauce over the chicken and peppers, stirring constantly for 1-2 minutes until the sauce reduces into a thick, glossy glaze.
While the sauce thickens, steam the broccoli florets in a steamer basket or microwave with a splash of water until bright green and tender.
Assemble the bowl by placing the warm brown rice at the base, topping it with the glazed chicken and peppers, and adding the steamed broccoli on the side.
Garnish with sesame seeds before serving.
