Sure! It's very simple. The only thing is, it could cost a little more because I used ribeye steaks. BUT, I pay attention to when they go on sale at the market. All I did was put my steaks in (3 for a our family of four, including my always hungry 6'2", 15 year old son) the cooker with one can (10 1/2 ounce) of french onion soup, one can of water, same amount of beef broth (I'm pretty sure it was a cup; I'll double check on that) and 2 tsp. of worschestshire sauce and let it cook. I added more onions close to the end because I love a lot of onions, plus I knew I was doing the French onion soup the next day. I shredded the steak with just a fork and knife, after it was very tender.
I bought sub rolls at the store and toasted the on both sides in the oven.
I also bought provolone cheese to melt over the top (son preferred his without cheese)
We put a cup of au jus to dip on each plate.
Then, the French onion soup was just heated up broth from the night before. I took the same sub bread and cut it into pieces and toasted them in the oven, added them to the broth and topped it with provolone cheese and melted in the oven (could do this in a microwave as well but I like the crispy brown edges and oven gives it).
You could probably use a cheaper cut of meat but I was not sure what to use and when I googled it, someone said the ribeyes were the best. I figured we got 2 meals out of it so it was justified

And actually, I got 3 meals because for lunch the next day , I had enough broth for one more bowl of soup!
