Prepare the brown rice according to package instructions or reheat pre-cooked rice until fluffy.
Dice the chicken breast into one-inch cubes and place them in a bowl with arrowroot starch, sea salt, and black pepper, tossing until each piece is lightly coated.
Heat the olive oil in a large non-stick skillet over medium-high heat and sear the chicken until golden brown and cooked through, approximately 6 minutes.
While the chicken cooks, whisk together the honey, tamari, minced garlic, and grated ginger in a small bowl to create the glaze.
Add the broccoli florets and sliced red bell pepper to the skillet with the chicken, sautéing for 3 minutes until the vegetables are tender yet crisp.
Pour the honey-garlic glaze over the mixture and stir constantly for 1 minute as the sauce bubbles and thickens into a glossy coating.
Spoon the cooked brown rice into a serving bowl and top with the glazed chicken and vegetable mixture.
Finish the dish by garnishing with thinly sliced green onions for a fresh bite.
