Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell peppers with half of the avocado oil and a pinch of sea salt.
Spread the vegetables in a single layer on the baking sheet and roast for 15-18 minutes until tender and slightly charred.
While the vegetables roast, pat the chicken breast dry with a paper towel and cut into bite-sized cubes.
In a small bowl, toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the remaining avocado oil in a large skillet over medium-high heat and sear the chicken for 3-4 minutes per side until golden and crispy.
In a small jar, whisk together the coconut aminos, honey, sesame oil, grated ginger, and minced garlic to create the glaze.
Reduce the skillet heat to low, pour the sauce over the chicken, and toss for 1-2 minutes until the glaze thickens and coats the meat.
Remove the roasted vegetables from the oven and serve them in a bowl topped with the crispy teriyaki chicken.
