Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the yellow potato, carrots, and onion into small, uniform half-inch cubes to ensure even roasting.
Toss the diced vegetables with olive oil and half of the sea salt and black pepper on the prepared baking sheet.
Roast the vegetables in the oven for 20 to 25 minutes until the potatoes are tender and golden brown.
While the vegetables roast, heat a large non-stick skillet over medium-high heat.
Add the ground turkey to the skillet, breaking it into small crumbles with a wooden spoon or spatula.
Season the turkey with the remaining sea salt, black pepper, garlic powder, and dried thyme.
Cook the turkey for 8 to 10 minutes until it is fully browned and no longer pink.
Remove the roasted vegetables from the oven and carefully fold them into the skillet with the cooked turkey.
Stir everything together for 1 to 2 minutes to allow the flavors to meld, then serve warm.
