Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced red bell pepper, and sugar snap peas on the baking sheet, then toss with avocado oil, sea salt, and black pepper.
Roast the vegetables for 15-18 minutes until they are tender and show slight charred edges.
While the vegetables roast, whisk together the coconut aminos, honey, toasted sesame oil, minced fresh ginger, and minced garlic in a small bowl.
Heat a non-stick skillet over medium-high heat and cook the diced chicken breast for 6-8 minutes until golden brown and cooked through.
Reduce the skillet heat to low, pour the teriyaki sauce over the chicken, and simmer for 2 minutes until the glaze thickens and coats every piece.
Plate the glazed chicken alongside the roasted vegetables and finish with a sprinkle of sesame seeds.
