Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets with avocado oil, sea salt, and black pepper on the baking sheet, spreading them in a single layer.
Roast the broccoli for 15-20 minutes until the edges are golden and crispy.
While broccoli roasts, season the chicken breast evenly with garlic powder and ground ginger.
Heat a medium skillet over medium-high heat and add the sesame oil.
Place the chicken in the skillet and sear for 6-7 minutes per side until the internal temperature reaches 165°F.
In a small bowl, whisk together the tamari and honey to create the teriyaki glaze.
Reduce the skillet heat to low, pour the glaze over the chicken, and turn the breast to coat thoroughly for 1-2 minutes until sticky.
Slice the chicken and serve it over the warm brown rice alongside the roasted broccoli.
Garnish the entire plate with sesame seeds for a final crunch.
