To kick things off, you’ll want to grab a knife, and expertly slice off the excess fat from the rump roast.
When you’ve accomplished this minor task, you will then want to toss that delicious meat into the slow cooker. Then, add in your beer, onion soup, and beef broth along with it. Set the slow cooker on “Low” and let it cook for roughly 7 hours.
After that lengthy cook period, you’ll want to head on over to your oven, and preheat that reliable kitchen appliance to 350°.
As that warms up, strategically split your rolls, and spread an equal amount of cannabis-infused butter in the interior of each one. Then, toss those buttered rolls into the oven to bake for a little under 10 minutes.
Once those rolls are prepared, pull them out of the oven, slice your meat on the bias, and proceed to place an equal amount of meat into each waiting roll.
Pour your sauce from the slow cooker into a dish or ramekin, and serve it alongside each sandwich for easy dipping. And, there you go - you’re done.
