Quick And Easy French Dip Sandwiches - cooking recipe

Ingredients

1 lb sliced dietz & watson london broil roast beef (or any rare deli sliced roast beef)
johnny's au jus sauce (2 parts water to 1 part concentrate)
1 medium onion, sliced thin
1 cup sliced mushrooms
4 tablespoons butter
4 rolls, submarine

Preparation

Heat au jus over medium heat to a boil. 2 parts water to one part Johnny's Au Jus Concentrate.
After au jus comes to a boil, lower heat to simmer and add sliced onions and mushrooms. Simmer for 30 minutes.
After 30 minutes, add roast beef. Simmer for 15 more minutes. This is why you want to start with rare roast beef. Beef will cook slowly, absorbing all the flavors of the au jus.
Whle meat is simmering, broil buttered sub rolls until brown and toasted.
Remove all components from au jus.
Dip face of toasted rolls in au jus, then add meat, onions and mushrooms.
Serve with au jus on the side, or however you like your French Dip!
