What makes a good sandwich

Or, rather, how a good sandwich can be a really simple one. I have a tendency to simply go too far with sandwiches, adding endless ingredients (salad, mayo, mustard, cheese, capers etc etc), when actually one really top quality kind of sandwich is a piece of good bread, some butter and some excellent cheese. I realised this the other day as I bit into a sandwich made of some lovely Italian bread from Gazzano's, lots of butter and a delicious goat's cheese from Neal's Yard and it was so damn tasty, not least because you could really taste all three ingredients and there is something especially delicious and salty about butter melting into bread in your mouth or, for that matter, cheese melting into butter into bread. Hmmm, is it clear that I'm writing this whilst rather hungry? Better nip to buy some cheddar for some pasta with chilli and cheese.
