Preheat your oven to 375°F (190°C) and line a small baking dish with parchment paper.
Heat the avocado oil in a small skillet over medium heat and sauté the finely diced onion and minced garlic until translucent and fragrant.
In a large mixing bowl, combine the ground beef, egg, almond flour, sautéed onion mixture, sea salt, black pepper, and dried oregano.
Use your hands to gently mix the ingredients until just combined, being careful not to overwork the meat which can make it tough.
Shape the mixture into a uniform loaf and place it in the prepared baking dish.
In a small ramekin, whisk together the tomato paste and honey, then brush the glaze evenly over the top of the meatloaf.
Bake for 25 to 30 minutes, or until the internal temperature reaches 160°F.
Let the meatloaf rest for 5 minutes before slicing to ensure it stays juicy and holds its shape.
