Ok, you might know about this or you might not, but this is particulary good if you are on an eternal diet and budget like me .....
Subway do a sub of the day, quite a bargain at £1.99 ....... usual price menu is pretty steep IMHO
HOWEVER the majority of the Subway stores allow you to turn your subway into a fairly large plated salad without having to pay extra. If you take advantage of their system you can get a large salad with all the stuff you like, the main meat of the sub plus cheese and topping for £1.99. I find this very filling and very helpful when I am too pooped to cook after the gym.
Good value examples are wednesdays when you get 4 slices of tasty ham or today when you get pepperoni, salami and ham. Many sites will also allow you to use the booklets of vouchers to be redeemed against the salads too.
Something to bare in mind instead of going to the chippy!
