Preheat oven to 400°F and line a baking sheet with parchment paper.
Peel and dice the sweet potato into half-inch cubes, then toss with half the olive oil and a pinch of salt.
Roast sweet potatoes for 20-25 minutes until tender and slightly caramelized on the edges.
While roasting, heat the remaining olive oil in a large skillet over medium heat.
Add the ground turkey to the skillet, breaking it apart with a spatula as it cooks.
Season the turkey with garlic powder, smoked paprika, salt, and pepper, cooking until no longer pink.
Dice the cucumber and slice the avocado into thin wedges.
Divide the roasted sweet potatoes and cooked turkey into bowls, then top with cucumber and avocado.
Finish with a bright squeeze of lime juice over the entire bowl.
