Sweet provided with cooked meal on wheels (7)
I believe the answer is:
caramel
'sweet' is the definition.
(I know that caramel is a type of sweet)
'cooked meal on wheels' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'on' says to put letters next to each other.
'wheels' becomes 'car' (wheels can informally mean a car).
'meal' is an anagram of 'amel'.
'amel' put after 'car' is 'CARAMEL'.
'provided with' is the link.
(Other definitions for caramel that I've seen before include "Soft sweet" , "Burnt sugar used for flavouring" , "Sugar solution heated till brown" , "Toffee-like sweet" , "Cooked sugar" .)
