Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with 0.5 tbsp of olive oil, sea salt, and black pepper directly on the baking sheet.
Roast the vegetables for 18-20 minutes until they are tender and the edges are beautifully charred.
While the vegetables roast, cut the chicken breast into 1-inch cubes and season them lightly with a pinch of salt.
Heat the remaining 0.5 tbsp of olive oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 6-8 minutes, turning occasionally, until the exterior is golden brown and crispy.
In a small bowl, whisk together the coconut aminos, finely minced ginger, and minced garlic.
Reduce the skillet heat to medium, pour the sauce over the chicken, and toss for 1-2 minutes until the glaze thickens and coats the meat.
Plate the roasted vegetables and top with the crispy teriyaki chicken, finishing with a sprinkle of sesame seeds.
