brandish

I'm a little stuck... Click here to teach me more about this clue!

'display' is the definition.
(I know that brandish is a is a more specific form of the action display)

'fibrous meal' is the wordplay.
'fibrous' becomes 'bran' (I can't explain this - if you can you should give a lot more credence to this answer).
'meal' becomes 'dish' (a dish is a particular meal).
'bran'+'dish'='BRANDISH'

Can you help me to learn more?

(Other definitions for brandish that I've seen before include "Display" , "Flourish (a weapon)" , "parade" , "Wave (in anger)" , "Wave (weapon) aggressively" .)
