Stick salad starter on bill (4)
I believe the answer is:
stab
'stick' is the definition.
(thesaurus)
'salad starter on bill' is the wordplay.
'starter' suggests taking the first letters.
'on' says to put letters next to each other.
'bill' becomes 'tab' (tab is a kind of bill**).
The first letter of 'salad' is 's'.
's'+'tab'='STAB'
(Other definitions for stab that I've seen before include "Wound with pointed weapon" , "shot in the dark?" , "Wound with blade" , "Try - skewer" , "Pierce with something pointed" .)
