Preheat your oven to 400°F and line a large rimmed sheet pan with parchment paper for easy cleanup.
Peel the sweet potato and cut into half-inch cubes, then dice the chicken breast into similar bite-sized pieces.
In a small glass bowl, whisk together the honey, extra virgin olive oil, tamari, and minced garlic until well combined.
Place the chicken and sweet potatoes on the prepared sheet pan, drizzle with half of the honey-garlic glaze, and season with sea salt and black pepper.
Toss the ingredients on the pan to ensure an even coating, then spread them out into a single layer.
Roast in the oven for 15 minutes, then briefly remove the pan to add the broccoli florets to the center.
Drizzle the remaining glaze over the broccoli, toss everything together one last time, and roast for an additional 10 to 12 minutes until the chicken is cooked through and the potatoes are tender.
