For a snack, I really like just heating up some frozen edamame in the microwave. Depending on the portion size, expect maybe 1 min of microwaving; let it cool off for a few mins because they always come out boiling in my experience. Salt em with kosher salt (or regular if you don't have) and squeeze the beans out of the pod in your mouth. Easiest way to get a little bit of veg and protein, hands down.

It's not the laziest, but this one can be prepped and made in the air fryer in <15 mins and it's honestly AMAZING. Could probably be really good with some heated up grilled chicken slices for protein, too. Requires a lot of fresh ingredients so it's more of a rare treat but it's sooooo good.
