OK, someone told me to toss a cheap roast into my crockpot and leave it for the day and then shred it and throw in some BBQ sauce and serve on buns. I have never done this before. I threw the roast in with some red wine, garlic and a tablespoon of cider vinegar. Do I need to do anything else while it is cooking? I am feeling a bit out of my depth here. Any suggestions will be gratefully received.
