Sandwich

As far as i'm here (almoust 2week) the different kind of sandwiches become the main meal for me. I mean that wracked thing from the self of the nearest Tesco/Sommerfield/Morrison`s, excusively after 7pm, reduced price. Most of them are nice if you just have about 5 minutes to grab something, but of course the home-made is beyond compare. What`s your best sandich experience?
