Preheat the oven to 425°F.
In a small bowl, whisk together the soy sauce, honey, sesame oil, grated ginger, and minced garlic to create the teriyaki marinade.
Place the chicken breast in a shallow dish, pour half of the marinade over the chicken, and let it marinate for at least 15 minutes (or up to 30 minutes for deeper flavor).
While the chicken marinates, chop the broccoli into florets, toss with a little olive oil (optional), salt, and pepper, and spread on a baking sheet.
Roast the broccoli in the preheated oven for 15-20 minutes until tender and slightly charred.
Heat a non-stick skillet over medium-high heat. Sear the marinated chicken breast for about 5-6 minutes per side, or until fully cooked through (internal temperature reaches 165°F).
In the final minute of cooking, drizzle the remaining marinade over the chicken in the skillet to create a sticky glaze.
If not already prepared, cook the brown rice according to package instructions.
Plate the sliced teriyaki chicken alongside the roasted broccoli and a serving of brown rice. Enjoy your balanced, flavorful meal!
