Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into 1/2-inch pieces, then toss with 1 tsp of olive oil and a pinch of sea salt and black pepper.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes, adding the broccoli florets to the tray for the final 10 minutes of roasting.
While the vegetables roast, season the chicken breast with the remaining sea salt and black pepper.
Heat the remaining 1 tsp of olive oil in a non-stick skillet over medium-high heat and sear the chicken for 5-7 minutes per side until golden and cooked through.
In a small bowl, whisk together the honey, tamari, and minced garlic to create the glaze.
Reduce the skillet heat to low, pour the honey-garlic mixture over the chicken, and simmer for 2 minutes until the sauce is bubbly, thick, and sticky.
Plate the chicken alongside the roasted sweet potatoes and broccoli, then drizzle any remaining glaze over the top and garnish with sesame seeds.
