Just a thread for everybody to put in their own ways & means of coping, not a competition
Well, stuff that I've learned - Never use your main oven, use a slow cooker or frying pan instead.
Add grated carrots and oats to all kinds of stew - you cant taste them but they make it more filling.
Have soup & pud nights instead of a main course.
Home made soup with bread. Almost anything can go into soup, fry it in butter & chuck it in.
Meals can also be things like Welsh Rarebit or beans or sardines on toast.
Rice pudding or semolina.
Yorkshire pud (in the old days they served it before the meat so that people would eat less meat

) Cheap sponge mixes added to fruit and jam/cream/custard poured over.
Make 2/3 small courses instead of 1 big huge one, people feel fuller that way.
Never forget the filling power of bread and butter and jam!
They say the HM laundry gloop is good but I cant be assed trying it, I know how to if need be though.
You don't need to heat bedrooms, at all. Might want to, but dont need to.
You don't need to buy stuff like kitchen roll/face wipes/hand cream/bath oil.You can live without them!
You don't need 30 different kinds of cereal- eat porridge and sprinkle different toppings on it instead.
If money is tight then first things to check are Sky, mobile phones, magazines, food & drink at work. It's amazing how much you can spend on a sandwich and drink from a machine.
If anybody's ever struggling I'd like to think they would come in here and ask or look for ideas, instead of suffering in silence and worrying themselves sick.
