Show off on board, appealing fare? (3,3)
I believe the answer is:
hot dog
'show off' is the definition.
(thesaurus)
'board appealing fare?' is the wordplay.
I cannot really see how this works, but
'appealing' could be 'hot' and 'hot' is present in the answer.
'fare?' could be 'dog' (dog food is a kind of food) and 'dog' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'on' is the link.
Can you help me to learn more?
(Other definitions for hot dog that I've seen before include "Sausage in a roll - acrobatic skier" , "food from a stand?" , "One panting" , "Sausage in bread-roll for thermal canine" , "Long roll containing sausage" .)
