Kebabs and enchilada starter surprisingly part of full English breakfast (5,5)
I believe the answer is:
baked beans
'part of full english breakfast' is the definition.
'kebabs and enchilada starter surprisingly' is the wordplay.
'starter' suggests taking the first letters.
'surprisingly' indicates an anagram.
The first letter of 'enchilada' is 'e'.
'kebabs'+'and'+'e'='kebabsande'
'kebabsande' anagrammed gives 'BAKED BEANS'.
(Other definitions for baked beans that I've seen before include "Full English breakfast essential?" , "veg too" , "Tinned vegetables" , "Haricots in tomato sauce" , "food campers might have" .)
