Place roast in crockpot and poke holes all over roast using a fork or knife. Add garlic and pepper. Pour juice from jars all around the roast and mound all the peppers on top
Cook on low 8-10 hours. Pull out shred, discarding fat and place meat back in juice while preparing buns. Toast buns on each side and top with cheese. Fill sandwiches with beef and peppers and juice on side to dip!
Notes
Toasting the buns help them hold up with the juice. You can certainly start with one jar of peppers if you are afraid of the spice. Add some water too. Next time you make the recipe you can add more if you like.
