Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the sliced bell peppers and broccoli florets with 0.5 tablespoons of olive oil, sea salt, and black pepper.
Spread the vegetables in a single layer and roast for 18-20 minutes until the edges are slightly caramelized.
While veggies roast, season the chicken breast with the remaining sea salt and black pepper.
Heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Sear the chicken for 5-7 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
In a small jar, whisk together the tamari, lemon juice, honey, minced ginger, and garlic.
Reduce the skillet heat to low, pour the sauce over the chicken, and simmer for 2 minutes until the glaze is thick and glossy.
Plate the chicken over the warm brown rice and serve alongside the roasted vegetables.
