I bought a vacuum pack of grass-fed chip steak, and I have no idea how to prepare it!! I was wanting to do a French-Dip type sandwich, but I have never made one before. I tried looking for recipes, but I could only find them for using either pre-cooked deli meat or a big roast. What would be the best way to cook the meat and still reserve the juices for making an au jus? I'm fairly adept in the kitchen, and can follow just about any recipe.. I just don't have a lot of experience with beef, since I just started eating it about a year ago.
