Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Slice the carrot into thin rounds and chop the red bell pepper into bite-sized pieces.
Place the broccoli florets, carrot rounds, and bell pepper pieces on the prepared baking sheet.
Drizzle the vegetables with 0.5 tbsp of olive oil and sprinkle with half of the sea salt, black pepper, and garlic powder.
Toss the vegetables to coat thoroughly and roast in the oven for 20 to 25 minutes until tender and slightly charred.
While the vegetables roast, season the chicken breast on both sides with the remaining sea salt, black pepper, garlic powder, and dried oregano.
Heat the remaining 0.5 tbsp of olive oil in a heavy-bottomed skillet over medium-high heat.
Place the chicken in the pan and sear for 6 to 8 minutes per side, or until the internal temperature reaches 165°F and the exterior is golden brown.
Remove the chicken from the pan and let it rest for 3 to 5 minutes to ensure it remains juicy before slicing.
Serve the sliced chicken alongside the roasted vegetables for a clean, nutrient-dense meal.
