French Dip Sandwiches

My family would eat this every week if I made it (and did for a while). It takes 2 minutes to put in the crock pot.

roast (I use a 3 lb. chuck tender but you could use anything)
packet of onion soup mix
1/3 cup soy sauce (I use the low sodium and sometimes use a little more)
WATER
beef bouillon (optional)
sub rolls
provolone cheese

Trim the fat off of the roast and put it in the crock pot. Mix soy sauce and onion soup mix and pour over roast. Add enough water to cover the roast. Drop in a bouillon cube if you want. Cook on low for 6-8 hours. Take meat out and cut or shred (it will fall apart!). Put meat and cheese on sub roll and toast for a few minutes. Dip it in the juice from the crock pot. You can tweak the juice to your taste. You might want a little more soy or no bouillon cube.
