Often trying to follow a bit of a restricted diet (i.e. not a lot of convenient restaurant type eating) requires spendign a little time planning ahead - both to prepare the food and also to figure out the best way to carry it with you. If you can get a cooler & carry that with you with the meal(s) that you need, it works. I carry a soft-side cooler w/ an ice pack and 5-6 meals w/ me every day to work. I have access to a fridge there, but I keep it all with me just in case someone decides to clean out the fridge or there's no room or whatever -- I'm completely self-reliant and am totally covered if i have to spend all day in meetings or have to go to our other building. I also have access to a microwave that I use to heat up most of my stuff because I use a lot of frozen vegetables. If you don't have access to a microwave but can do the cooler thing, chicken & spinach salad or something that you dn't have to heat up works good. If you get really desperate, those Tuna Sensations or whatever they are, flavored tuna in a pouch are great! All you need is literally a fork. And they taste pretty good!
