Preheat your oven to 400°F (200°C).
On a large baking sheet, toss the broccoli florets with 0.5 tbsp of olive oil and the sea salt until evenly coated.
Roast the broccoli for 15-20 minutes until the edges are tender and slightly charred.
While the broccoli roasts, whisk together the honey, tamari, minced garlic, grated ginger, and toasted sesame oil in a small bowl.
Cut the chicken breast into bite-sized pieces and season with the black pepper.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 5-7 minutes, turning occasionally, until golden brown and cooked through.
Reduce the heat to medium-low and pour the honey-garlic sauce over the chicken.
Simmer for 2-3 minutes, stirring constantly, until the sauce thickens into a glossy, sticky glaze that coats the chicken.
Plate the honey-garlic chicken alongside the roasted broccoli and garnish with red pepper flakes for a hint of heat.
