Directorial meals? (5)

I believe the answer is:
board
'meals?' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for board that I've seen before include "See 13 across" , "Food - table - directors" , "See 9" , "Get on - governing body" , "panel" .)
