Fears to be converted to traditional English food (5,4)
I believe the answer is:
roast beef
'traditional english food' is the definition.
(I've seen this before)
'fears to be converted' is the wordplay.
'converted' indicates anagramming the letters.
'fears'+'to'+'be'='fearstobe'
'fearstobe' with letters rearranged gives 'ROAST-BEEF'.
'to' is the link.
(Other definitions for roast beef that I've seen before include "Traditional English food" , "Sunday meat?" , "Typical English dish" , "Joint" , "Typically 7 down dish" .)
