Saute the onions and garlic in olive oil and cook for several minutes. Add the sliced mushrooms and some chopped fresh parsley and saute until mixture is soft. Set aside to cool. In a large bowl combine all ingredients EXCEPT ADD ONLY HALF of the Mushroom Sauce. (Throw in some more chopped fresh parsley if desired.) Mix to combine but do not overmix or meatloaf will become heavy and dense! Form into a loaf shape in a baking pan. Top the loaf with the remaining mushroom sauce. Bake in a 375-400 degree oven for about 1 1/4 hours or until internal temp is 160 degrees. Remove meat from the pan and allow to rest while you make the gravy from the drippings in the pan.

GRAVY-Place pan on stove and whisk in 1/4 cup of flour. Stir up browned bits in the pan and stir for several minutes. Then add 2 cups water and continue to stir.
