Philly French Dip

I wasn't quite sure what to call this, because it's kind of a mix between a Philly Cheese Steak and a French Dip. I'm not even sure where the idea came from! My mom just threw it together one evening and we all loved it, it's been a favorite ever since.

Hoagie Rolls
1.5 - 2 lbs roast beef
Au Jus Mix
One onion
One package sliced mushrooms
Olive oil
Shredded mozzarella
Miracle Whip or Mayonnaise

• Prepare Au Jus mix as described on the package. Because the meat is going to be boiled in the mix, you'll want to double or triple the water. Heat mix to a boiling and add roast beef.
• Cut onion in to slices and the slices in to quarters, put in skillet (either electric or stove top work with this recipe) with mushrooms and a coating of olive oil (about 2 tbsp). Sautee until both mushrooms and olives are soft.
• Put Miracle Whip or mayonnaise on hoagie roll, add roast beef, top with mushroom/onion mix and mozzarella.

This recipe is good for those that don't like onions and/or mushrooms, because you can simply not add them and just eat a regular french dip!
