1 roast (cheapest one at the store - don't buy a nice one)
2 loaves of day old bread from Jimmy Johns ($.40 here!)
2 packs of Au Jus gravy powder mix
Stir up 1 Au Jus packet with 1-2 cups of water (depending on the size of your crock pot) and place the roast in the crock pot with the water/ powder mix. Add water until it's about half way up the pot.
Let the crock pot cook it on low all day.
When you get home from work, take a fork and shred up the meat (you can do this while it's still in the crock pot). It should just pull apart really easily.
Heat up the second Au Jus packet according to the directions.
Cut the bread in half length-wise and then again width-wise so you have 4 pieces of bread for 2 sandwiches/ loaf. Butter the inside of the bread and place it on a cookie sheet butter side up. Add cheese if you want (I don't like it but Jared does) on top of one of the buttered sides.
Broil the bread until it's toasted.
Put the shredded meat on the bread and make sandwiches then dip it in the Au Jus you heated up.
