Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets, sliced bell pepper, and chopped zucchini with half of the olive oil and a pinch of salt and pepper.
Spread the vegetables in a single layer and roast for 15-20 minutes until tender and slightly caramelized.
While vegetables roast, season the chicken breast with the remaining salt and pepper.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until golden and cooked through.
In a small bowl, whisk together the coconut aminos, minced ginger, minced garlic, and sesame oil.
Pour the sauce into the skillet with the chicken during the final 2 minutes of cooking, allowing it to bubble and thicken into a glossy glaze.
Slice the chicken and serve it over the roasted vegetables, drizzling any remaining glaze from the pan and garnishing with sesame seeds.
