Report eating British food (5)
I believe the answer is:
table
'food' is the definition.
(table is a kind of food)
'report eating british' is the wordplay.
'report' becomes 'tale' (tale is a kind of report).
'eating' indicates putting letters inside.
'british' becomes 'b' (abbreviation e.g. in BBC).
'tale' going around 'b' is 'TABLE'.
(Other definitions for table that I've seen before include "Board; data list" , "Put forward for formal discussion" , "Board off which dinner's eaten" , "shelf" , "Dummy hand (bridge)" .)
