Preheat your oven to 375°F and line a small loaf pan with parchment paper.
Heat the avocado oil in a small skillet over medium heat and sauté the finely diced onion, celery, and minced garlic until translucent and fragrant.
In a large mixing bowl, combine the ground turkey, cooked wild rice, egg, sautéed vegetables, dried oregano, sea salt, and black pepper.
Gently mix the ingredients by hand until just incorporated, ensuring you do not overwork the meat to maintain a tender texture.
Transfer the mixture to the prepared loaf pan, smoothing the top with a spatula.
Spread the tomato paste evenly over the top of the loaf to create a savory glaze.
Bake for 35 to 40 minutes, or until the internal temperature reaches 165°F.
Allow the meatloaf to rest for 5 to 10 minutes before slicing to ensure the juices redistribute.
