There is a little restaurant in Texas that we go to every holiday season. I look over the menu over and over and every single time I order the French Dip sandwich. Steak, mushrooms, bell peppers, onions and all topped with cheese and soaked in au jus! What an incredible combination. This recipe takes a little bit of a lighter approach with the flank steak over the sirloin – I prefer this over the extra fat in a sirloin.

Mushroom French Dip

A twist on a classic. Au jus, mushrooms, peppers and so much juicy goodness.
