Hot Roast Beef Sandwiches

This is the easy way to make hot roast beef sandwiches.  There are more sophisticated versions of this sandwich, but this is the quick and easy one!

4 Steak Rolls
3 Cups of Water
1 Packet of McCormick Au Jus Gravy Mix (or Brown Gravy Mix works too)
1 Small Onion, sliced
Mushrooms
1/2 lb Roast Beef (from the deli counter works)
Horseradish (optional)

In a 2 qt saucepan, whisk together the water and gravy mix.  Cook over medium heat.  Add the mushrooms and onion and simmer for about 10 minutes.  Turn the heat to low and add the roast beef.  Using two forks shred the roast beef a little.

Slice the rolls.  Spread some horseradish on the roll if desired.  Scoop some meat, mushrooms, and onion on to the roll.  Pour some gravy into a ramekin for dipping.
