Preheat your oven to 425°F.
Rinse and pat dry the chicken breast, then season both sides lightly with salt and pepper.
In a small bowl, mix the balsamic vinegar and honey to create the glaze.
Heat half the olive oil in a skillet over medium-high heat. Sear the chicken breast for about 2 minutes per side until golden, then transfer it to a baking dish.
Pour half of the glaze over the chicken, reserving the remainder for after baking.
Trim and halve the Brussels sprouts, toss them in the remaining olive oil, and season with salt and pepper. Spread them out on a baking sheet.
Place the chicken in the oven and roast for 15-18 minutes, or until fully cooked. Simultaneously, roast the Brussels sprouts for about 20 minutes, stirring once halfway through, until they are crispy on the edges.
While the chicken and sprouts are roasting, prepare the fluffy brown rice as per package instructions if not already cooked.
Once the chicken is done, drizzle with the reserved glaze. Plate the chicken with the roasted Brussels sprouts and a side of brown rice.
Serve warm and enjoy your balanced, flavorful meal.
