'freeze some chicken for later?' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'stay informed' is the wordplay.
'stay' becomes 'keep' (keeping is a kind of staying).
'informed' becomes 'abreast' (I've seen this in another clue).
'keep'+'abreast'='KEEP ABREAST'

'and' is the link.
