Thinly slice cucumbers into a large bowl. I used a vegetable slicer for more uniform slices but you can also slice with a knife. Stir in salt and cover cucumbers well. Let cucumbers sit for 30-60 min and sweat. Adding salt to the cucumbers will cause the water to “sweat” out and leave so you won’t have a bowl of water later on.

In a small saucepan heat white vinegar, water, and sugar until sugar is dissolved.

Drain cucumber slices from any juices in the bottom. Pour vinegar solution over drained cucumbers and add remaining vegetables and shallots. Stir well. Cover and refrigerate for one hour until cool and severe chilled.
