Preheat your oven to 375°F (190°C) and line a small baking sheet or loaf pan with parchment paper.
In a small skillet over medium heat, sauté the finely diced onion and celery with a tablespoon of water until they are soft and translucent.
In a large mixing bowl, combine the ground turkey, cooked wild rice, egg, sautéed vegetables, coconut aminos, thyme, garlic powder, sea salt, and black pepper.
Gently mix the ingredients by hand until just combined, being careful not to overwork the meat to maintain a tender texture.
Shape the mixture into a compact loaf on the prepared baking sheet.
Spread the tomato paste evenly over the top of the loaf to create a savory, concentrated glaze.
Bake for 35 to 40 minutes, or until the internal temperature reaches 165°F (74°C).
Remove from the oven and let the meatloaf rest for 5 to 10 minutes before slicing to ensure it stays juicy.
