Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Dice the yellow potato into small 1/2-inch cubes and break the broccoli into small, bite-sized florets.
In a medium mixing bowl, combine the ground turkey, potato cubes, and broccoli florets.
Drizzle with extra virgin olive oil and sprinkle with dried rosemary, garlic powder, sea salt, and black pepper.
Toss the ingredients thoroughly until everything is evenly coated in the oil and seasonings.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the turkey is broken into small chunks for even cooking.
Bake for 20 to 25 minutes, tossing halfway through, until the potatoes are fork-tender and the turkey is fully cooked through.
Remove from the oven and serve immediately while the potatoes are still golden and crisp.
