I did pot roast the other day. I read someones advice to cut the chuck roast I to strips, so did that, then added carrots and potatoes, a can of beef broth and a slow cooker packet of tavern pot roast seasoning (can't remember brand, maybe Campbell's, but its a liquid) amnd cooked high pressure for 45 minutes, NPR. It was so good, the falling apart roast that I could never get in my crock pot.
