To me this is akin to adding chips to one's sandwich, an indulgence I frequent particularly for long hikes or days skiing on the mountain. That added crunchy texture is magic. Apparently we're "hardwired" to crave that crunchiness as during our evolution if a neanderthal was eating something crunchy it meant they were consuming fibrous and salutary vegetables.
We've been adding Kimchi to just about every dish we've made of late. Pickle your own in advance or buy a supply from the grocery store. Kimchi adds a great layer of flavor & spice to eggs, toast and stir frys. Highly recommend.
I wish I had a rule by which I could codify how to discover additions like this...looking forward to the responses of others!
