I spend too much on food and can only do so because I work one day a week at the moment to top up the basic state pension which is my only other income.
For one person I spend about £60 - £70 weekly, on average, which includes household items like bleach, detergent, loo paper, shampoo etc.
I usually buy some chocolate, maybe a packets of biscuits in case of an unexpected visitor, occasionally some veggie crisps, the rest is lots of veg, fruit and salad stuff, with some expensive things like avocados and olives, one lot of meat which makes 2 meals (organic chicken breasts, a pork chop, loin chops or stewing steak) and some frozen fish such as salmon or a fish pie, other meals are vegetarian using pulses or eggs. When the job is no longer there it will be beans on toast and an apple!
