Penny with second tray of food (7)
I believe the answer is:
platter
'tray of food' is the definition.
'platter' can be an answer for 'tray' (thesaurus). I'm not certain of the 'of food' bit.
'penny with second' is the wordplay.
'penny' becomes 'p' (short for pence).
'with' is a charade indicator (letters next to each other).
'second' becomes 'latter' (latter can mean the second of two mentioned things).
'p'+'latter'='PLATTER'
Can you help me to learn more?
(Other definitions for platter that I've seen before include "old record?" , "Large flat serving dish" , "Charger" , "pop record" , "Large flat plate" .)
