I'm going away for the long weekend to a smaller city, will be there for 3 days and I'm working 12 hours a day, possibly more...so the combination of working non-stop and staying in someone else's place (without my kitchen) means I won't be able to cook properly while I'm there. I don't want to buy rubbish food for all of my meals so I'm planning to do a huge cook-up before I go and pack myself lots of food!

So I'm looking for healthy, filling, easy to eat on the go, tasty food items to make.
Anyone have suggestions?
