Mushroom Gravy

We had crepes again last night, they really are so good.  I was in a more savory mood so a whipped up a mushroom gravy to go with mine, and it was simply splendid.  I was really happy I had some leftover, because it also was excellent up top of my grilled chicken and mashed potatoes tonight.
