Two adults and one adult who is here three nights a week and probably two weekends a month when we might have 6 to 8 people for a weekend meal.
Including all toiletries, cleaning stuff, beers, occasional spirits, etc., I'd say we spend between £800 and £1000. It also covers breakfasts and my lunches. We never have a takeaway. We eat well but not terribly extravagantly. This week for example:
Tonight: roast chicken, New potatoes, Greek salad, coleslaw, and something like profiteroles for 4
Sunday: roast lamb for 4 and a roulade.
Monday: Bol
Tuesday: chicken curry with some samosas and rice from Saturday's chicken.
Weds: something like pork chops and cous cous with salad
Thurs: omelette and salad
Fri: plaice, fries, salad or green veg (plaice was heavily reduced and is in the freezer).
DH likes a desert and I tend to buy the Gu ones or similar. Always have in fruit and cheese.
Usually do big shops at Tesco. Nice meat and fish from Waitrose.
If it were just DH and me, I reckon it would probably come to £500/600.
Undoubtedly it could be done for less but we are fortunate enough to be able to have what we fancy. When DS and Dd's BF are here it amazes me how much they can pack away. Both late 20s and very active.
The cats are separate and probably come to about £150pcm. Only the best for them and they complement with mice!
