Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Chop the broccoli into bite-sized florets and slice the red bell pepper into thin strips.
Place the vegetables on the baking sheet and toss them with 0.5 tablespoons of olive oil, sea salt, and black pepper.
Season the chicken breast with garlic powder and the remaining 0.5 tablespoons of olive oil, then place it on the baking sheet next to the vegetables.
Roast in the oven for 15 minutes, or until the chicken is nearly cooked through and the vegetables are starting to soften.
While the chicken roasts, whisk together the honey, tamari, and minced garlic in a small bowl to create the glaze.
Remove the sheet from the oven and brush the honey-garlic glaze generously over the chicken breast.
Return the tray to the oven for an additional 5 minutes until the glaze is bubbling and the chicken reaches an internal temperature of 165°F.
Let the chicken rest for 3 minutes before slicing it into strips and serving alongside the roasted vegetables.
