In a large bowl, toss the diced sweet potatoes with 1 tablespoon of olive oil, salt, pepper, garlic powder, and paprika. Spread them out on one side of a baking sheet.
Season the chicken breasts with salt, pepper, and cumin. Heat the remaining tablespoon of olive oil in a large skillet over medium-high heat. Sear the chicken breasts for about 5-7 minutes on each side, until fully cooked and golden brown. Remove from heat and let rest before slicing.
While the chicken is cooking and sweet potatoes are roasting, add the chopped red bell pepper and broccoli florets to the other side of the baking sheet. Roast everything for an additional 15-20 minutes until the vegetables are tender and slightly caramelized, stirring halfway through.
In meal prep containers, divide the roasted sweet potatoes, chicken slices, black beans, and roasted vegetables evenly among each container.
Garnish with fresh cilantro, if desired, and serve lime wedges on the side for squeezing over the bowl.
