Place the cucumbers in a sieve or colander, mixed with the salt. Place over a bowl (to catch the water) and place a plate or something heavy onto the cucumbers to press them down. Leave for 30 minutes then drain well and wipe dry.
Combine all ingredients in a medium bowl and mix well. Keeps in the refrigerator a few days, though you may have to stir it to recombine if it starts to separate.
