ethandron....Heinz in tins are one of my stand-bys !
It dates from my camping days, right back when I was a boy. For instance, a tin of creme of tomato soup, with lots of crusty bread is simply wonderful.....ditto with creme of mushroom !
On Monday, when I had a drive up in to the Beacons, to look at the snow, I took some soup in a flask, and although the crusty bread made a bit of mess in the car, the soup was wonderful !
Baked Beans can be used in all sorts of ways.....with grated cheese on top, or by spreading some Marmite of the toast first !
