Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with olive oil, half of the sea salt, and half of the black pepper on the prepared baking sheet.
Roast the vegetables for 15 to 18 minutes until they are tender and show slight caramelized edges.
While the vegetables roast, season the chicken breast with the remaining salt and pepper.
Heat a large non-stick skillet over medium-high heat and sear the chicken for 6 to 7 minutes per side until the internal temperature reaches 165°F.
In a small bowl, whisk together the honey, tamari, and minced garlic.
Reduce the skillet heat to low, pour the honey-garlic mixture over the chicken, and simmer for 2 minutes until the sauce becomes a thick, glossy glaze.
Remove from heat, slice the chicken, and serve immediately over the roasted vegetables, garnished with sesame seeds.
