I'm a little stuck... Click here to teach me more about this clue!

'a movable feast?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'mess hall one we turned' is the wordplay.
'turned' indicates anagramming the letters.
'mess'+'hall'+'one'+'we'='messhallonewe'
'messhallonewe' with letters rearranged gives 'MEALS-ON-WHEELS'.

'into' acts as a link.

Can you help me to learn more?

(Other definitions for meals on wheels that I've seen before include "fare at little cost to the elderly?" , "InterCity rail fare" , "Women see halls (anag) - welfare service" .)

I've seen this clue in the Sydney Morning Herald.
