Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets on the baking sheet with 0.5 tbsp of olive oil, sea salt, and black pepper.
Roast the broccoli for 15-18 minutes until the edges are slightly charred and tender.
While the broccoli roasts, whisk together the honey, tamari, toasted sesame oil, minced garlic, and grated ginger in a small bowl.
Season the chicken breast with a small pinch of salt and heat the remaining 0.5 tbsp of olive oil in a skillet over medium-high heat.
Sear the chicken for 5-6 minutes per side until golden brown and cooked through.
Lower the heat to medium-low and pour the honey-garlic mixture into the skillet.
Simmer the sauce for 1-2 minutes, spooning it over the chicken until it thickens into a glossy glaze.
Slice the chicken and serve immediately alongside the roasted broccoli, garnished with sesame seeds.
