You see little packages of these at stores, but the kind of thing you are after is meat bites, cheese bites and nuts, and maybe boiled eggs.
Quick, not sloppy, not messy, where you can have 16 total bites but maybe only take four bites four separate times.
I’d meal plan that based on calories, and include that protein drink as a back pocket item in case you need it.
In this scenario, celery sticks and carrot sticks are probably also useful.
.1. Cheeses and summer sausages, maybe some crackers.
.2. Can you put a crock pot or insta-pot in your break room? Because there are a ton of ways to make high protein meals that rewire little more than dumping ingredients in, turning it on and walking away.
