Both the beef and potatoes didn't work particularly well on Sunday for some reason so we had just one roast lunch and thought about what to do with the remains.
The joint was minced, some of the gravy added:
Although a little dry due to lack of further gravy, it tasted far better than the original roast! I had enough beef to create another 'pie' but with normal mash on top. The meat that was left, had all the gravy added to it, some tomato puree and hot water. This we had as roast beef soup - delicious!
So then, the meat stretched to 3 meals for 2 people and soup for 2 people, quite good.
