Feast is meagre -- Lent possibly? (10)

I believe the answer is:

regalement

'feast' is the definition.
(thesaurus)

'meagre lent possibly?' is the wordplay.
'possibly?' indicates an anagram (I've seen 'possibly' mean this).
'meagre'+'lent'='meagrelent'
'meagrelent' anagrammed gives 'REGALEMENT'.

'is' acts as a link.

I've seen this clue in The Telegraph.
