I love broad beans but they can be a bit floury bitter and flavourless if allowed to get big. Two packs of beans from Sainsbury's was enough for two people!!!
Boil the beans, run them under cold water in the colander and skin them by making a nick on one side with a fingernail and pinching them out from the other side. Easy and quick when you get the knack. Chop half a small onion very finely indeed - almost to a puree if you can be bothered, and shred a very few tips of sage leaves into the tinyest filaments that you can. Stir these into the beans (which are a lovely and unusual green). When you are ready for them, heat some butter in a small saucepan, pop beans et al in and warm through - now what could be easier than that? (The sage needs to be only just detectable - be careful - it can easily take over. You are not a heavy handed Venetian!)
