Preheat your oven to 375°F (190°C) and line a small baking dish with parchment paper for easy cleanup.
Heat the olive oil in a small skillet over medium heat and sauté the finely diced onion until soft and translucent.
Add the minced garlic to the skillet and cook for an additional 30 seconds until fragrant, then remove from heat to cool slightly.
In a large mixing bowl, combine the ground turkey, egg, almond flour, sautéed onion and garlic, dried oregano, sea salt, and black pepper.
Gently mix the ingredients by hand until just incorporated, taking care not to overwork the meat to maintain a tender texture.
Shape the turkey mixture into a uniform loaf shape and place it onto the prepared baking dish.
Spread the tomato paste evenly over the top of the loaf to create a concentrated savory glaze during baking.
Bake for 35 to 40 minutes, or until the internal temperature reaches a safe 165°F (74°C).
Allow the meatloaf to rest for 5 to 10 minutes before slicing to ensure the juices redistribute throughout the meat.
