Nick gets a little salt? (5)
I believe the answer is:
pinch
I believe this clue is a double definition.
'nick' is the first definition.
(both can mean steal)
'a little salt?' is the second definition.
(a pinch of salt)
'gets' acts as a link.
(Other definitions for pinch that I've seen before include "Squeeze painfully" , "Grip tightly; steal (colloq.)" , "Squeeze between the fingers" , "Steal; small quantity" , "Steal (informal); squeeze" .)
