I have used Japan Cucumber where in I could not go to Little India to get the normal one. It almost tasted the same.
Remove skin and cut 1 no of cucumber into cubes or small slices. Add salt and required green chutney or pudina chutney(Grind Pudina/mint leaves wtih green chilli to fine paste) and mix well. Add little lemon juice.
Salad is ready. This can be had as it is or with lunch or dinner.
