What about spices, condiments, oil, drinks other than soda (in some places tap water is barely drinkable if drinkable at all, fruits and veggies for salads, nuts and other snacks, dessert, spreads for challah, coffee, cereal, etc.
Some people calculated 1 egg per adult for breakfast but it’s not enough. We eat 2, plus 2 slices of toast, plus veggies and fruit. We make it ourselves but I’m assuming it comes out to over $5 per person per meal, which is 60 just for breakfast for the week just for the adults. And so on.
I can go on and on but we spend way more than 400 a week for a family of 4, if you’re including pantry staples. Maybe were just bigger eaters than you all.
I live in Israel so we have guests frequently for the meals and yeshiva boys can eat a lot!!
Our biggest expense is probably produce because its the only way to keep healthy without needing specialty items.
