Table mat so, redesigned for breakfast item (5,5)
I believe the answer is:
melba toast
'breakfast item' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'table mat so redesigned' is the wordplay.
'redesigned' indicates an anagram.
'table'+'mat'+'so'='tablematso'
'tablematso' is an anagram of 'MELBA TOAST'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for melba toast that I've seen before include "crispy breakfast" , "food from the grill" , "Thin crisp food" .)
