Beef & Cheddar Sandwich

While trying to figure out what to do with my remaining thin sliced, deli-cut Angus top round roast beef, I came across a series of videos on YouTube of people replicating Arby’s Beef & Cheddar. So I thought I’d give it a shot.
First, I toasted a couple slices of sourdough with a little butter. I turned off thee heat on the skillet, set the toast aside and tossed in about 1/3 LB of my roast beef, just to warm it slightly.
Meanwhile, to make my Arby Sauce I mixed ketchup, Worcestershire sauce and a splash of apple cider vinegar.
To make the cheese sauce I melted a couple tablespoons of butter, mixed in a couple tablespoons of flour. After blended, I added about 1/4 cup of milk. So, a Béchamel sauce. Once well mixed, I added 3 slices of chopped up cheddar cheese and stirred till smooth.
Construction: Bread, red sauce, warmed beef, cheese sauce and the top bread.
SO GOOD!
