Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Slice the sweet potato into uniform thin wedges and toss them in a bowl with the olive oil, half of the sea salt, and half of the black pepper.
Spread the wedges in a single layer on the baking sheet and roast for 20-25 minutes, flipping halfway through, until they are tender and the edges are slightly crisp.
While the potatoes roast, place a non-stick skillet over medium-high heat and add the ground turkey.
Cook the turkey until browned and cooked through, breaking it into small crumbles and seasoning with the smoked paprika and the remaining salt and pepper.
In a small mixing bowl, combine the Greek yogurt, minced garlic, and lemon juice, whisking until the aioli is smooth and creamy.
Arrange the roasted sweet potato fries on a plate, pile the seasoned ground turkey on top, and drizzle generously with the garlic aioli.
Garnish with freshly chopped green onions and serve immediately.
