[Review] M&S Marks and Spencers Wafer thin roast beef

I love wafer thin roast beef because it reminds me of roast dinners at school with gravy.
The roast beef at M&S is really good, it can be used for sandwiches but I had it for dinner with gravy.

M&S uses the topside of the beef so each slice is moist and tender, simply delicious as roast dinner or in a sandwich.
