Ok moving away from unhealthy for now lets have a look at some of the healthier options for lunch. Apart from mums home packed lunches that some are still lucky enough to have lets look at take away. fist up is subway have a look at there menu-

Next up is sumo salad-
http://www.sumosalad.com/
i have to say this would by far be my favourite (make your own salad is the best try it!)

The next is rolls choice-

i personally have not had a sandwich from here I'm a pretty picky person when it comes to food.

I would also say a lot of Chinese stores sell healthy food but the top 3 by far are the best.
