Poor Man's Roast. Oops, I did it again!

I caught then end of a discussion on the radio the other day, where the 'person of interest,' was talking about a cheap meal--Poor Man's Roast. All it had was three ingredients with maybe a bit of oil and added pepper. It consisted of layering sliced potatoes, onions and bacon and then baking it. I can give that a lift, I thought. So I did the above with the addition of a layer of greens from the garden and then mixing in a packet of Magi chicken soup and grated cheese on the top, right at the end of cooking. Anyone can do this and I reckon it would easily feed a hungry group of four. I used 5 potatoes, two onions and a packet of bacon. All costs about $10 max. Go do it and leave the takeaways alone for a while.
