Preheat oven to 400°F and line a baking sheet with parchment paper.
Peel and dice the sweet potato into half-inch cubes, toss with half the olive oil and a pinch of salt, then roast for 20 minutes until crispy.
While potatoes roast, heat a skillet over medium heat with the remaining olive oil and brown the ground turkey, seasoning with garlic powder, onion powder, salt, and pepper.
Bring a small pot of water to a boil, gently lower in the eggs, and simmer for 6.5 minutes for a jammy yolk before transferring to an ice bath.
Place fresh spinach in the base of a bowl and top with the warm turkey and roasted sweet potatoes.
Peel and halve the eggs, place them on top, and finish with a generous dollop of Greek yogurt.
