From about 3lbs of beef (1.4 kg) for a cost of just shy of £15, I got - initially - four portions of roast dinner, 2 adult and 2 kids size.
The next day, I put the leftovers in the freezer for half hour, and then ran about half through a meat slicer, on about 2mm. From this, I made 4 portions of roast beef sandwiches, served on baguettes with rocket (arugula) and horseradish. The rest - about 3/4 lb (350g) I diced very roughly for stew (I got 4 good sized adult portions from it)
I have a large number of recipes for "meat and barley" stews - the one linked below uses swede rather than potato, but they're all similar. Use a small amount of meat, and stretch it using barley, vegetables, and flavour it with stock and herbs.
Meat, used frugally, and padded out with vegetables, herbs, spice, and broth, served with bread, is what used to be know as "pottage", the famously stereotypical dish of British peasants. All of the various dishes - be it the below, or Irish stew, or Scotch broth, or the others, are (as best as I can tell, and I'd love others' opinions) variants on pottage that have survived to modern day.
The one I made (beef with carrots, onions, potato and beef, with the barley) is known as "lobscouse", is a regional variant from Liverpool, and is why Liverpudlians are known as "Scousers".
Purists will say that it *has* to have carrot, potato and onion. I'm trying not to stray *too far* from the original dishes, but I also believe that as a "thrift" meal, adding swede instead of/as well as potato does not render it inadmissible.
I probably added more barley than is traditional, but, uh, I really like barley (some recipes don't use it at all, just the meat and vegetables)
During the cooking, if using potato but not, one would mash the potato a little once it's softened, and that would add as the thickener.
It's worth noting that as well as herbs like thyme, marjoram or rosemary - which would be available in many a kitchen garden, that it would be seasoned *heavily* with pepper (often white pepper, not black), which would give it a certain amount of heat. Without getting into the whole "spice" conversation right now, we did use more pepper than I think is generally understood, given that's what we had access to for everyday meals.
