A scare as careless young man makes a dish (6,5)
I believe the answer is:
caesar salad
'a dish' is the definition.
(Caesar salad is an example)
'a scare as careless young man' is the wordplay.
'careless' is an anagram indicator.
'young man' becomes 'lad' (lad can mean a boy or young man).
'a'+'scare'+'as'='ascareas'
'ascareas' with letters rearranged gives 'caesarsa'.
'caesarsa'+'lad'='CAESAR SALAD'
'makes' acts as a link.
(Other definitions for caesar salad that I've seen before include "Dish containing lettuce" , "Dish of dressed lettuce with croutons" , "Seasoned mixture of cos lettuce and croutons" , "food" , "leaves meal - with 14a" .)
