Bear inside offers to discuss food (8)
I believe the answer is:
eatables
'discuss food' is the definition.
'eatables' can be an answer for 'food' (I've seen this in another clue). I'm unsure of the 'discuss' bit.
'bear inside offers' is the wordplay.
'inside' means to look at the middle letters.
'offers' becomes 'tables' (I can't explain this - if you can you should give a lot more credence to this answer).
The centre of 'bear' is 'ea'.
'ea'+'tables'='EATABLES'
'to' acts as a link.
Can you help me to learn more?
(Another definition for eatables that I've seen is " food!".)
