Best thing for lunches is make your own.
Cheese and marmite sarnies arent 'health food' but they're a damn site better than takeaways, sausage rolls, pasties, and the shit pre-packed stuff you get in supermarkets.
Stick a yoghurt and some other little bits in to beat the boredom and you're laughing. School-style packed lunches FTW!!
