Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into half-inch pieces, then place them on the baking sheet with the broccoli florets and sliced red bell peppers.
Drizzle half of the olive oil over the vegetables and sprinkle with a pinch of sea salt and black pepper, tossing well to coat evenly.
Roast the vegetables in the oven for 20-25 minutes, tossing halfway through, until the sweet potatoes are tender and the broccoli edges are slightly charred.
While the vegetables roast, pat the chicken breast dry and season both sides with the turmeric, garlic powder, paprika, and the remaining salt and pepper.
Heat the remaining olive oil in a cast-iron or stainless steel skillet over medium-high heat.
Once the pan is hot, add the chicken and sear for 6-7 minutes per side until the internal temperature reaches 165°F and the crust is a deep golden hue.
Remove the chicken from the pan and let it rest for 5 minutes to lock in the juices before slicing it into strips.
Plate the roasted vegetables alongside the sliced golden chicken and serve immediately.
