Hot Open Face Roast Beef Sandwiches with Taters

Andy Anderson !


The main part of the recipe is in the making of a beef roast specifically for use in beef sandwiches. That’s not to say, if you have a regular beef roast that you can’t use it.

You allow the beef to slowly cook in the oven, and then assemble the sandwich with a pile of yummy mash taters. The smells that fill the house are amazing.

I have also served this many times without the bread... Just the yummy beef, potatoes, and gravy.

So, you ready… Let’s get into the kitchen.
