There is me, DH and DD3 living at home. I spend between £50 and £80, and I'd really rather spend less. We are vegetarian, so there is no meat or fish and I always cook from scratch. We get takeaway about three times a year (usually when DH wants some unhealthy food!) and we rarely eat out - not more than once every other month. We do buy one or two bottles of wine or beer each week, so that keeps the price up. It does annoy me that food is so expensive. I mainly shop at Asda as we live really close to the store, but try to get to Lidl or Aldi if I can for cheaper bits. I do like the fruit and veg from Lidl as they are good quality and inexpensive, but have always been disappointed with Aldi veg. If we have cakes they are only ever home made - they taste nicer, cost less and aren't full of preservatives.
I realise I might be sounding like a goody-goody! But we are on a fairly tight budget and couldn't afford to spend more. Plus I prefer home made food.
