I am currently 2 weeks into a construction job. I pothole. Sometimes it's strenuous, sometimes it's easy. I'm mobile for part of the day. But the crazy thing is (it's even allowed according to labor laws), is were not allowed to go anywhere for lunch. We have to bring a lunch. No leaving in company vehicles the boss says...

Well I've brought my lunch but I just brought conventional foods like bread for sandwiches. This was before I started lchf/Paleo...

So what would someone recommend packing a lunch for a work day?
