When I make this salad, I don't do anything fancy. I don't whisk the dressing together prior to mixing the salad together. I don't salt my cucumbers first, in an attempt to draw their moisture out.
All I do is chop the veggies and dump them in the bowl. I pour everything else on top (honestly, I don't even measure) and stir it to combine.
Taste it a few minutes later and adjust the flavors a bit, if necessary (if my dill is old, which it often is, I add a bit more).
Then, let it sit until dinner time. If there's any leftover, I eat it out of the bowl while cleaning up.
