Preheat your oven to 400°F and line a large sheet pan with parchment paper for easy cleanup.
Peel and cube the sweet potato into 1-inch pieces, then cut the chicken breast into similar bite-sized chunks.
In a small bowl, whisk together the honey, tamari, minced garlic, and extra virgin olive oil until well combined.
Place the sweet potato cubes on the sheet pan, drizzle with half of the honey-garlic sauce, and season with sea salt and black pepper.
Roast the sweet potatoes for 15 minutes, then remove the pan from the oven and add the chicken chunks and broccoli florets.
Drizzle the remaining sauce over the chicken and broccoli, tossing everything together to ensure an even coating.
Return the pan to the oven and roast for an additional 15 to 20 minutes until the chicken is cooked through and the potatoes are tender.
Sprinkle with sesame seeds before serving for a little extra crunch and visual appeal.
