Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the cubed potatoes with olive oil and half of the sea salt and black pepper on the prepared baking sheet.
Roast the potatoes for 15 minutes while you prepare the meatloaf mixture.
In a medium bowl, combine the ground turkey, egg, almond flour, finely diced onion, minced garlic, and the remaining salt and pepper.
Form the turkey mixture into a compact loaf shape and place it on the baking sheet next to the partially roasted potatoes.
In a small ramekin, whisk together the tomato paste and coconut aminos until smooth, then brush half of this glaze over the top of the meatloaf.
Return the baking sheet to the oven and bake for another 20-25 minutes, applying the remaining glaze halfway through, until the meatloaf reaches an internal temperature of 165°F and the potatoes are crispy.
