Preheat your oven to 400°F and pierce the sweet potato several times with a fork to allow steam to escape.
Place the sweet potato on a parchment-lined baking sheet and roast for 45 to 50 minutes until the center is soft.
While the potato roasts, cook the chicken breast by poaching or pan-searing until it reaches 165°F, then shred it with two forks.
In a small mixing bowl, combine the shredded chicken, rinsed black beans, cumin, chili powder, sea salt, and black pepper.
Once the sweet potato is finished, slice it down the center and gently fluff the inside with a fork.
Stuff the chicken and bean mixture into the potato and return it to the oven for 5 minutes to ensure everything is heated through.
Remove from the oven and top with a dollop of Greek yogurt, diced avocado, fresh cilantro, and a squeeze of lime juice.
