Leftovers make hot beef sandwiches like you used to get in restaurants (not out of a box).
1 beef roast (any kind)
1 envelope Hidden Valley Ranch salad dressing mix *
1 envelope brown gravy mix
1 envelope Italian dressing mix *
1/2 cup warm water
Vegetables, if desired
* If salt is a concern or you like things less salty, I suggest that you use only 1/2 envelope of both the Hidden Valley Ranch and Italian dressing mixes.
Place roast in slow cooker.
Mix contents of all 3 envelopes and sprinkle over roast.
Pour water into the bottom of the crock pot.
Cover and cook on LOW for 6 to 7 hours.
Add veggies to the crock, if desired. I usually add at least carrots and onions. You can add celery, bell pepper or whatever else you like.
