I'm in so much turmoil about this, I can't decide!
I reckon it will be something like:
1) fresh soft granary bread
2) slices of boiled egg
3) mayo
4) bit of pepper at this point
5) a few leaves of really crisp lettuce
6) perfect avocado slides
7) maybe one of two slices of those lovely plum tomatoes too, but not too many, we don't want a soggy sandwich
