Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Chop the red bell pepper and zucchini into bite-sized pieces.
In a large bowl, toss the broccoli, bell pepper, and zucchini with 0.5 tbsp of olive oil and a pinch of sea salt.
Spread the vegetables in a single layer on the baking sheet and roast for 15-20 minutes until tender and slightly charred.
While the vegetables roast, pat the chicken thighs dry and season both sides with sea salt, black pepper, garlic powder, and smoked paprika.
Heat the remaining 0.5 tbsp of olive oil in a heavy skillet over medium-high heat.
Place the chicken in the skillet and sear for 5-7 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 3 minutes.
Plate the chicken alongside the roasted vegetables and garnish with chopped fresh parsley.
