About £900 for two adults, a teenage DS and a second DS with ARFID. DH and teenage DS eat lunch at work/school Monday to Friday but DS with ARFID and I eat all meals at home. ARFID is really limiting as I have to buy the same things from the same shops each week. For things like strawberries for example, when out of season, he can eat £4 worth of strawberries in a day. Same with raspberries - £4 worth in another day. Ditto lychees.
The £900 includes all cleaning and laundry stuff but not booze (DH and I are barely drinking at the moment).
We eat pretty well though - lots of meat and fish, sides with main meals, fruit and veg, soft drinks etc. I’ve bought a £11 tray of sushi for teenage DS to eat tonight, for example, but mostly I cook from scratch. I batch cook at least once a week and use up leftovers eg I had four pints of milk on the verge of going off last week so made a vat of rice pudding and froze it.
I’m not actively trying to reduce our food bill, but I’ve really noticed prices going up. I need to do a stock take of the freezer so that next week I only buy what we need to make meals with what we already have. I also have a pretty well stocked pantry, so lots of tins, spices and herbs and dried pasta, rice etc to use as a base for meals.
As I’ve typed, I’ve talked myself into seeing how little I can spend next week by making meals using up what we have.
