I love a really good French Dip with a hot cup of Au Jus on the side to dip the sandwich into on a chilly day. While it does not get overly cold in Georgia, there are some times when there is a chill in the air and with fall setting in I needed to find some warm comfort food alternatives. I found a recipe that I thought was worth trying and I AM SO GLAD WE DID. This Mushroom French Dip Sandwich is not only affordable, it is delicious! If you do not have a lot of time to make the Au Jus yourself you can always sub it for a package of mushroom soup or even onion soup, just add water/ heat it on the stove and call it good.
