Food wrapped in newspaper? (3)
I believe the answer is:
pap
'food' is the definition.
(pap is a kind of food)
'wrapped in newspaper?' is the wordplay.
'wrapped in' indicates a hidden word.
'PAP' can be found hidden inside 'newspaper'.
(Other definitions for pap that I've seen before include "Mushy food for children or invalids" , "Soft mushy food for infants or invalids" , "Palindromic semi-liquid food as for babies or invalids" , "Bland soft food" , "Type of diet that doesn't require chewing" .)
