Shama-il Tirmidhi Chapter 29, Hadith Number 6 (193).

Rubayyi bint Mu’awwidh ibn Afraa radiyallahu anha says, My uncle Mu’aadh ibn Afraa sent me with a plate of fresh dates, which had small cucumbers on it, to Rasoolullah sallallahu alaihe wasallam. Rasoolullah sallallahu alaihe wasallam relished cucumbers. I took this to him. At that time some jewellery had been sent to Rasoolullah sallallahu alaihe wasallam from Bahrain. He took a handful from it and gave it to me.

Besides the previously mentioned benefits of cucumbers and dates, it makes the body plump too. Sayyiditina Aisha radiyallahu anha relates that, After my marriage, when the time came for me to go and live with Rasoolulla sallallahu alaihe wasallam, my mother thought I be a bit plump and my build become better. She gave me cucumbers and dates to eat. As a result my body became nice and plump.

It is related in a weak hadith that Sayyiditina Aisha radiyallahu anha said that Sayyidina Rasoolullah sallallahu alaihe wasallam ate cucumber with salt. It is possible that he at times ate it with salt and at times with dates. Sometimes one prefers something that is sweet and at other times a thing that is salty.
