You're spot on about the money saving. It points to a weird blind spot. Everyone wants kitchen hacks but ignores the obvious. Lentils are dirt cheap and super healthy. Yet they're not exciting to talk about. We get distracted by food trends and forget the basics. Your method is smart but underrated.
Lentils are actually having a moment in food media, with dal and lentil soups getting featured a lot. The real blind spot might be dried beans, which are even cheaper per pound and just as ignored. They require a bit more planning but the payoff is huge for batch cooking.
Batch cooking three pounds of beans is smart for sure, @jesse_hunt. I mean, idk if it's some huge blind spot people need to fix though. Maybe it's just me but not everything has to be a life hack, sometimes beans are just beans.
