Toast? Well, we enjoy it (4,6)
I believe the answer is:
good health
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'toast? well we enjoy' is the wordplay.
I cannot quite see how this works, but
'toast?' could be 'health' (I've seen this before) and 'health' is found within the answer.
'well' could be 'good' (synonyms) and 'good' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for good health that I've seen is " Cheers!".)
