Very dull food? (7)
I believe the answer is:
noodles
'food?' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for noodles that I've seen before include "Thin strips of pasta for old ones" , "Far Eastern food" , "Narrow strips of pasta, or slang heads" , "Geese" , "Oriental pasta" .)
