Reportedly grab a dal, when served up - it's healthy-ish food (6,5)
I believe the answer is:
caesar salad
'food' is the definition.
(Caesar salad is an example)
'reportedly grab a dal when served up' is the wordplay.
'reportedly grab' becomes 'caesars' (I can't explain this - if you can you should give a lot more credence to this answer).
'when served up' says the letters should be written in reverse.
'dal' backwards is 'lad'.
'caesars'+'a'+'lad'='CAESAR SALAD'
'it's healthy-ish' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for caesar salad that I've seen before include "Seasoned mixture of cos lettuce and croutons" , "Dish containing lettuce" , "Dish of dressed lettuce with croutons" , "Lettuce-based dish" , "leaves meal - with 14a" .)
