There is no right answer to this question, if I had to, and when I had to, I could live frugally (spaghetti hoops on toast being a dinner !) . I consider food one of the joys of life and I haven't a notion of living frugally. The older I get and particularly due to Covid that is my view. Our actual food bill is higher due to Covid but we are saving a fortune on dining out. And we dined out very well indeed.
Maybe a better question should be how much can I get the food bill down to, for those needing to do so. Without feeling like the family are hard done by.
Wise words. I remember having to keep an eye on the cost after I graduated so now I enjoy not doing that. It’s nice to be able to buy things like fillet steak and monkfish if you want to. But you could do it for much less if needs be.
