Nuts a wandering man sold (7)
I believe the answer is:
almonds
'nuts' is the definition.
(almond is a kind of nut)
'a wandering man sold' is the wordplay.
'a wandering' is an anagram indicator.
'man'+'sold'='mansold'
'mansold' anagrammed gives 'ALMONDS'.
(Other definitions for almonds that I've seen before include "Nuts used to make marzipan" , "Man sold (anag.)" , "Fruits for marzipan" , "Sold man on kind of nuts" .)
