Even a bag of dry beans has doubled in recent memory.
I grew up eating so-called “peasant cuisine”, so I’ve got plenty of cheap recipes that I actually enjoy eating.
Steam 1 batch escarole - save the water.
Cook a box of ditalini in the water so it reabsorbs the vitamins.
(add a little oil & salt to keep from sticking and raise the temp a bit)
Strain
Add beans (kidney, cannelloni, whatever).
Sprinkle with grated parmesan.
You could eat for a week.
(btw - I sometimes save the pasta water - I pour it hot to kill the weeds in the sidewalk cracks, or let it cool and water the garden).
Costs a few bucks and feed
