Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Cut the chicken breast into uniform 1-inch cubes and trim the broccoli into bite-sized florets.
In a small mixing bowl, whisk together the honey, tamari, sesame oil, minced garlic, and grated ginger until well combined.
Place the chicken and broccoli on the prepared sheet pan, season with sea salt and black pepper, and drizzle with half of the honey-garlic sauce.
Toss everything together on the pan to ensure an even coating, then spread into a single layer.
Roast in the oven for 15 to 18 minutes, or until the chicken is cooked through and the broccoli edges are slightly caramelized.
While the chicken roasts, warm your pre-cooked jasmine rice in a small saucepan or microwave.
Remove the sheet pan from the oven, drizzle the remaining sauce over the hot chicken and veggies, and serve immediately over the fluffy rice.
