I'd say around €250 per week. 2 adults + one mid-teen + cat
That includes cleaning / pet food / alcohol etc.
I truly don't know how people manage to feed so many on such tiny amounts, I admire them but I fail miserably.
We eat fairly standard stuff (no quail or lobster!) but we cook a lot and most meals have lots of components. For example if we have pasta we will always have fresh basil, fresh parmesan, marinaded olives, garlic bread, salad as well as the ingredients for the dish itself.
Similarly we have chilli we will have tortillas / tacos, cheese, sour cream, avocadoes for guacamole, coriander, spring onions, japalenos, salsa
Etc - so the 'main' meal might be simple but the other bits add up. We live 30mins from the nearest shop and have a teen so we always have plenty of snacks in stock for them and their friends.
We're very lucky to be able to shop the way we do and I'm grateful for it every time I load up a trolley
