Preheat oven to 350° F (177 °C), and grease or oil a 9x4 standard size loaf pan. In a medium size skillet over medium high heat melt the 2 tablespoon butter. Add onions, garlic and mushrooms. Stir occasionally and heat for 5 minutes. Turn off heat and add 2 tablespoon Worcestershire sauce. Stir in, remove from stove top and let cool.
In a large mixing bowl combine: 1 ¼ lb ground turkey, ⅓ cup tomato sauce, 1 large egg, 1 ½ tablespoon flax meal or ¼ cup almond meal, ¾ teaspoon sea salt, and ½ teaspoon black pepper. Combine thoroughly.
Add all the butter mushroom garlic mixture to the meatloaf mixture. Stir and combine thoroughly. Add half of meatloaf mixture to the loaf pan and spread across the bottom of the pan with a rubber scraper or the back of a spoon, *seen in photo above.
Layer 3 slices of uncooked bacon on top of the meatloaf layer, as seen in photo above. Layer the optional cheese slices on top of the bacon, *seen in photo above.
Add the other half of meatloaf mixture to the top bacon & cheese layer, and spread across the loaf pan to cover the last layer, *seen in photo above. Bake in oven for 60 minutes. Might need a little more or less time, depending on your oven. Remove from oven, and serve.
