Ballet to satisfy one's appetite with disappointingly feeble content (4,4)
I believe the answer is:
swan lake
'ballet' is the definition.
(ballet by Pyotr Tchaikovsky)
'satisfy one's appetite with disappointingly feeble content' is the wordplay.
I cannot quite see how this works, but
'with' could be 'w' (abbreviation) and 'w' is present in the answer.
'content' could be 'an' (AN is an example) and 'an' is found within the answer.
'satisfy' could be 'slake' (as in slaking one's thirst) and 'slake' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
'to' is the link.
(Other definitions for swan lake that I've seen before include "Ballet by Tchaikovsky" , "piece of elegance" , "Tchaikovsky's ballet about noble bird" , "Well-known ballet" , "stage production" .)
