One of my favorite sandwiches was a French dip sandwich with tender slices of roast beef and the beef broth for dipping.
We I made this version with mushrooms and a savory onion and mushroom broth. I ditched the hi-carb, hi-calorie hoagie roll and used Dave’s Killer bread. Their hamburger buns work great.
This is easy as it uses mushroom broth for the jus although you can make your own soup with dried mushrooms.
The mushrooms are braised so you don’t have to watch them cook.
I recommend using a horseradish sauce with this. Grate some fresh horseradish into your Veganaise or cashew mayo. I have not found any horseradish sauce without cream, egg or both.

Notes
This is a Snap Pea Sheep recipe.
Fresh horseradish can vary considerably. Some is extremely pungent and hot while others are bland and tasteless. You must taste to determine your preference.
I add it to a bit of Veganaise. You can use the mayo sub of your choice, hummus or a bit of non dairy yogurt. You can also just sprinkle some on the sandwich or jus.
