Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Spread the cooked brown rice onto the baking sheet, drizzle with half of the olive oil, and roast for 12-15 minutes until the edges are golden and slightly crispy.
Pat the chicken breast dry and season both sides evenly with sea salt, black pepper, and garlic powder.
In a small bowl, whisk together the raw honey and Dijon mustard until well combined.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sear the chicken for 6 minutes per side until the internal temperature reaches 165°F.
While the chicken is searing, steam the broccoli florets for 5 minutes until they are bright green and fork-tender.
Lower the skillet heat to medium-low, pour the honey mustard mixture over the chicken, and turn the breast several times until the sauce reduces into a thick, glossy glaze.
Plate the roasted rice, top with the glazed chicken breast, and serve with the steamed broccoli on the side.
