Return on your seeds

I like all kinds of peas but they tend to come all at once and picking them takes a long time. I gave up growing podding peas because podding is so boring. I was bored after 2 meals of mangetout this year, quite happy to see them end quickly. I just want a few peas to snack on occasionally, not have to eat them every day for weeks on end.

French beans are similarly relentless but are more versatile in the kitchen.

I would also factor in the effort spent building structures to support peas & beans.
