He's given meals or bread, possibly (7)
I believe the answer is:
boarder
'he's given meals' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'or bread possibly' is the wordplay.
'possibly' is an anagram indicator.
'or'+'bread'='orbread'
'orbread' with letters rearranged gives 'BOARDER'.
Can you help me to learn more?
(Other definitions for boarder that I've seen before include "one that's getting on plane" , "Live-in school pupil" , "pirate?" , "Attacker at sea possibly repelled" , "Resident pupil" .)
