Food to satisfy, from what we hear (4)
I believe the answer is:
meat
'food' is the definition.
(meat is a kind of food)
'satisfy from what we hear' is the wordplay.
'satisfy' becomes 'meet' ('meet' can be a synonym of 'satisfy').
'from what we hear' indicates a 'sounds like' (homophone) clue.
'meet' is a homophone of 'MEAT'.
'to' acts as a link.
(Other definitions for meat that I've seen before include "Eg, beef or pork" , "17 [ESSENCE]" , "grub, say" , "Spam, ham, lamb etc" , "Flesh for eating" .)
