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 half-inch pieces, then toss them on the baking sheet with half of the olive oil, sea salt, and smoked paprika.
Season the chicken breast with garlic powder, black pepper, and the remaining salt, then place it on the other side of the baking sheet.
Roast for 20 to 25 minutes until the chicken reaches an internal temperature of 165°F and the sweet potatoes are fork-tender.
While the oven does the work, shred the red cabbage and dice the cucumber into small, uniform pieces.
In a large serving bowl, combine the cooked quinoa and rinsed black beans as your nutrient-dense base.
Once cooked, slice the chicken into thin strips and arrange it over the quinoa along with the roasted sweet potatoes, cabbage, and cucumber.
Whisk the remaining olive oil with the lime juice and drizzle it over the entire bowl just before serving.
