Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into 1/2-inch pieces, then toss them on the baking sheet with olive oil, sea salt, and black pepper.
Roast the sweet potatoes for 15 minutes while you prepare the remaining ingredients.
In a small bowl, whisk together the coconut aminos, sesame oil, honey, garlic powder, and ginger powder to create the teriyaki glaze.
Cut the chicken breast into bite-sized chunks and trim the woody ends off the asparagus.
Add the chicken and asparagus to the baking sheet with the potatoes, drizzle the teriyaki glaze over everything, and toss well to ensure an even coating.
Return the sheet to the oven and roast for another 12 to 15 minutes until the chicken is cooked through and the sauce has thickened into a glossy glaze.
Garnish the dish with sesame seeds and serve immediately while hot.
