Perhaps rasher rightist goes after bonanza on vacation (5)
I believe the answer is:
bacon
'perhaps rasher rightist' is the definition.
I can't judge whether this defines the answer.
'goes after bonanza on vacation' is the wordplay.
'goes' becomes 'con' (I am not sure about this - if you are sure you should believe this answer much more).
'after' is a charade indicator (letters next to each other).
'on vacation' says to hollow out the word (remove centre letters) (after the inside letters have vacated the word).
'bonanza' with its centre removed is 'ba'.
'con' after 'ba' is 'BACON'.
Can you help me to learn more?
(Other definitions for bacon that I've seen before include "Francis ---, Ir. painter" , "Shakespeare's ghost, some say" , "Breakfast food" , "early scientist" , "Salted pig-meat" .)
