Dish gone west (4)
I believe the answer is:
stew
'dish' is the definition.
(type of dish)
'gone west' is the wordplay.
'west' anagrams to 'STEW'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for stew that I've seen before include "Lazy person" , "overheated condition" , "Dish of meat and mixed vegetables" , "Slow-cooked dish of meat and vegetables" , "A hole, a fix" .)
