You can also buy dry soy beans. They're not popular human food not because they taste bad or are hard to eat, but because they take so damn long to cook. However, stick them in an Instant Pot for an hour, and you can walk away while they cook.

They're mild, a little nutty, but also a little waxier in texture than most beans (similar to edamame in that way, but closer to other beans than edamame when they're cooked from dried).

I still haven't found a great use for them other than as a slightly weird substitute for other beans, because there's not a lot of recipes around for them (because they historically took like 3 hours to cook), but I personally enjoy them just fine.
