More than one mouthful of mushrooms, gobbling seconds (7)

I believe the answer is:

morsels

'more than one mouthful' is the definition.
(morsel is a kind of mouthful)

'mushrooms gobbling seconds' is the wordplay.
'mushrooms' becomes 'morels' (morel is a kind of mushroom).
'gobbling' is an insertion indicator.
'seconds' becomes 's'.
'morels' going around 's' is 'MORSELS'.

'of' acts as a link.

I've seen this clue in The Times.
