Preheat your oven to 375°F and prepare a small baking dish by lightly greasing it with olive oil.
In a bowl, combine the lean ground turkey, egg, almond flour, mixed dried herbs, salt, and pepper. Mix until just combined to maintain a loose texture.
Place the turkey mixture into the prepared baking dish, shaping it into a small loaf.
Bake the meatloaf for about 20-25 minutes until the internal temperature reaches 165°F.
Meanwhile, heat the teaspoon of olive oil in a small skillet over medium heat. Add the diced onion and sauté until translucent.
Add the sliced mushrooms to the skillet and cook until they soften and release their moisture, about 3-4 minutes.
Pour in the turkey broth and allow the mixture to simmer for another 2-3 minutes until slightly thickened. Season with a pinch of salt and pepper to taste.
Once the meatloaf is cooked through, remove it from the oven and let it rest for a couple of minutes.
Serve a slice of the meatloaf topped with the warm mushroom gravy and enjoy your hearty meal.
