We do, but the problem is cost. It’s one of those “of these three attributes, pick two” between healthy, delicious, and cheap.

Healthy, delicious and cheap exists (at home at least). But it is very labour intensive and it will go bad in a couple of days.
I think that's the difference between EU and US. After living in both, in the EU, we shop nearly every day, while in the US it's ~ every weekish or longer.
