Various roasted nuts, including last of peanuts (8)
I believe the answer is:
assorted
'various' is the definition.
(synonyms)
'roasted nuts including last of peanuts' is the wordplay.
'nuts' indicates an anagram (nuts can mean crazy).
'including' is an insertion indicator.
'last of' says to take the final letters.
The final letter of 'peanuts' is 's'.
'roasted' with letters rearranged gives 'asorted'.
'asorted' enclosing 's' is 'ASSORTED'.
(Other definitions for assorted that I've seen before include "Classified" , "Containing various different kinds" , "Manifold" , "Of different kinds put together, like sweets" , "Motley" .)
