Preheat your oven to 425°F and line a large baking sheet with parchment paper for easy cleanup.
Slice the potato into thin, uniform matchsticks to ensure even cooking and maximum crispiness.
In a medium bowl, toss the potato strips with the olive oil and half of the sea salt and black pepper until well coated.
Spread the potatoes in a single layer on the baking sheet and roast for 20 to 25 minutes, flipping halfway through, until golden brown.
While the fries roast, heat a non-stick skillet over medium-high heat and add the ground turkey, breaking it apart with a spatula.
Cook the turkey until browned, then stir in the tomato puree, chili powder, cumin, garlic powder, and the remaining salt and pepper.
Lower the heat and let the chili simmer for 5 to 7 minutes until the sauce has thickened and the flavors are well combined.
Remove the crispy fries from the oven and pile them onto a plate, immediately topping with the hot turkey chili.
Sprinkle the shredded sharp cheddar over the chili so it melts from the residual heat, then garnish with diced red onion and fresh cilantro.
