Preheat your oven to 375°F (190°C) and lightly grease a standard muffin tin with avocado oil or coconut oil.
Place the grated zucchini in a clean kitchen towel and squeeze firmly over the sink to remove as much excess moisture as possible.
In a large mixing bowl, combine the ground turkey, cooked lentils, squeezed zucchini, grated carrots, and finely diced onion.
Add the egg, oat flour, garlic powder, sea salt, and black pepper to the bowl.
Using clean hands or a spatula, mix the ingredients until just combined, being careful not to overwork the turkey meat which can make it tough.
Divide the mixture evenly into six muffin cups, smoothing the tops with the back of a spoon.
Spread a small amount of tomato paste over the top of each mini loaf to create a savory glaze.
Bake for 20 to 25 minutes, or until the internal temperature reaches 165°F and the edges are slightly golden.
Remove from the oven and let the loaves rest in the pan for 5 minutes to allow the juices to redistribute before serving.
