Place your celery, onions and carrots in the bottom of a slow cooker.
Top your veggies with Lipton Onion soup mix.
Next, pour a beer over the top of your veggies along with a cup of beef broth.
Next, place your roast on top.
Slow cook on low for 6-8 hours until your roast is cooked through and tender.
Using two forks or a Mix N Chop, shred the roast.
Serve over mashed potatoes or with buttered bread!
