Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Cut the chicken breast and the peeled sweet potato into uniform 1-inch cubes, and chop the bell pepper into bite-sized pieces.
In a small mixing bowl, whisk together the honey, tamari, olive oil, minced garlic, and grated ginger until well combined.
Place the chicken cubes, sweet potato, broccoli, bell pepper, and snap peas onto the prepared sheet pan.
Sprinkle the sea salt and black pepper over the ingredients, then pour the honey-garlic glaze over the top.
Toss everything thoroughly with tongs or clean hands to ensure an even coating, then spread into a single layer.
Roast for 20 to 25 minutes, tossing the ingredients halfway through, until the chicken is cooked through and the sweet potatoes are fork-tender.
Remove from the oven and garnish with sesame seeds before serving warm.
