Share food caught by European (5)
I believe the answer is:
piece
'share' is the definition.
(piece is a kind of share)
'food caught by european' is the wordplay.
'food' becomes 'pie' (pie is a kind of food**).
'caught' becomes 'c' (cricket abbreviation).
'by' is a charade indicator (letters next to each other).
'european' becomes 'e' (abbreviation e.g. EU).
'pie'+'c'+'e'='PIECE'
(Other definitions for piece that I've seen before include "constituent" , "Bishop, for one" , "Portion, coin, item" , "Bit - part" , "American gun" .)
