Preheat your oven to 400°F and line a baking sheet with parchment paper.
Peel and cube the sweet potato into bite-sized pieces, then toss them with half of the olive oil, cumin, and a pinch of sea salt.
Season the chicken breast evenly with garlic powder, sea salt, and black pepper.
Arrange the chicken and sweet potatoes on the prepared baking sheet and roast for 20 to 25 minutes until the chicken is cooked through and potatoes are tender.
While roasting, rinse the black beans and dice the red bell pepper.
Place the fresh spinach in a large bowl and top with the black beans and diced bell peppers.
Once the chicken is finished, let it rest for 5 minutes before slicing it into strips.
Assemble the bowl by adding the sliced chicken and roasted sweet potatoes to the greens.
Drizzle the entire bowl with lime juice and the remaining olive oil before serving.
