Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Scrub the sweet potato thoroughly and pierce the skin several times with a fork to allow steam to escape.
Place the potato on the baking sheet and roast for 45 to 50 minutes until the center is soft and the skin is slightly caramelized.
While the potato is roasting, heat the olive oil in a non-stick skillet over medium-high heat.
Add the ground turkey to the skillet and season with the garlic powder, sea salt, and black pepper.
Cook the turkey while breaking it into small crumbles until it is fully browned and no longer pink.
In a small mixing bowl, combine the part-skim ricotta cheese with the lemon juice and whisk vigorously until smooth and light.
Once the sweet potato is finished roasting, slice it open lengthwise and fluff the flesh with a fork.
Spoon the seasoned ground turkey into the sweet potato and top with a generous dollop of the whipped ricotta.
Garnish the dish with freshly chopped chives and a sprinkle of hemp seeds for added texture.
