Scoop a portion of salad leaves (5)
I believe the answer is:
ladle
'scoop' is the definition.
(as in ladling out scoops of food)
'a portion of salad leaves' is the wordplay.
'a portion of' says the answer is hidden in the clue.
'LADLE' is hidden in the letters of 'salad leaves'.
(Other definitions for ladle that I've seen before include "Soup or sauce server" , "Large long-handled spoon" , "Perhaps stock holder" , "Serving implement" , "Long-handled spoon for serving soup" .)
