Steak Sandwich - How to Make the Most out of Leftovers

Yesterday I wrote about the perfect sirloin that I cooked for Jef's birthday and today I want to talk about how to take steak leftovers and make a completely new and delicious meal out of them.

First off, there are a couple of things that I like to keep on deck at all times, one of them being onions. I use onions in almost everything that I cook, so having them on available is a must! Secondly, I am a big fan of dijon mustard. There are so many things that you can make with dijon aside from using just a spread (salad dressings, flavoring in soups etc.) and it's extremely useful to have around. Without further adieu here is the recipe for the best steak sandwich ever!

Ingredients:

• 1/2 onion
• Dijon mustard
• left over steak 
• butter
• french bread (really any good, crusty bread will do)
• EV olive oil 
• cheese (optional and really anything will work)

Directions:

First off, turn your oven to the broil setting. You would rather have the oven waiting on you, then you waiting on the oven...

Next, in a pan on medium heat, add enough oil to coat the pan. Once hot, add in the onion then salt and pepper. While the onions are cooking take out your steak and cut thin slices (about 1/8 in thick). You want them to be thin enough to chew through in one bite, and not so thick that you pull the entire piece of meat out when you sink your teeth in. 

Slice your bread and then butter the inside. Place inside oven for about 2 minutes, just enough so that the edges are brown and the butter is melted. Remove from oven and spread dijon. 

Add your steak to the pan with the onions, tossing generously (remember we don't want to overcook our perfectly cooked steak, just want to warm up the fat enough so that it will melt in our mouths). I had some left over mushrooms, so I added them in at this step too. 

After about two minutes, remove the mixture from the stove and place inside the bread. Here you can add cheese if you want. 

Return the entire sandwich to the oven for one last warming. After two/three minutes or until cheese is melted remove from oven and ENJOY.

This has long been a favorite dish of mine and it's really making use of left over steak, something I know a lot of people have issues with. What's the most creative way you use left overs? Let me know! thefrugalfoodies@gmail.com
