Appears with food (3)
I believe the answer is:
pea
'food' is the definition.
(pea is a kind of food)
'appears with' is the wordplay.
'with' says the answer is hidden in the clue.
'PEA' is hidden within 'appears'.
(Other definitions for pea that I've seen before include "Tiny stone" , "garden plant" , "It grows in 23 Down" , "Pulse vegetable" , "Legume" .)
