Put the ground beef in a frying pan and turn it on medium.  Cook the ground beef thoroughly.  If you are using real onions, add them now and cook them with the beef.

Add the stock in.  First, I just have to show you the stock.  Look how gelled it is!

Add the stock to the pan and let it "melt."  You can see the layer of fat on top of mine in this picture.

Mix in the arrowroot powder (and onion powder).

Cook it on medium-high until it begins to boil and thickens.  Now it is done!  Wasn't that easy?

Serve over mashed potatoes.  Yummy!
