Preheat your oven to 400°F and line a large sheet pan with parchment paper to ensure the honey glaze doesn't stick.
In a small mixing bowl, whisk together the olive oil, honey, tamari, minced garlic, sea salt, black pepper, and red pepper flakes.
Place the cubed sweet potatoes and diced chicken breast on the prepared sheet pan, drizzle with half of the glaze, and toss to coat.
Spread the mixture into an even layer and roast for 15 minutes, allowing the potatoes to soften and the chicken to begin browning.
Add the broccoli florets to the pan, drizzle with the remaining glaze, and toss everything together once more.
Roast for another 10 to 12 minutes until the broccoli is tender and the chicken reaches an internal temperature of 165°F.
Remove from the oven and serve immediately, scraping any caramelized glaze from the pan onto the chicken.
