Men consuming half a loaf with fruit (5)
I believe the answer is:
melon
'fruit' is the definition.
(type of fruit)
'men consuming half a loaf' is the wordplay.
'consuming' indicates putting letters inside.
'half a' indicates taking half.
'loaf' with half the letters taken is 'lo'.
'men' going around 'lo' is 'MELON'.
'with' acts as a link.
(Other definitions for melon that I've seen before include "Cantaloupe fruit" , "Large round fruit" , "Eg, cantaloupe, galia" , "Honeydew fruit" , "Killing" .)
