American idiot's back making posh belly of veal for main course (7)
I believe the answer is:
seafood
'course' is the definition.
(type of food)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for seafood that I've seen before include "Such as prawns, tuna" , "Shellfish, marine fish" , "The "surf" of a surf 'n' turf dish" , "Edible fish, shellfish etc from the oceans" , "Eaten fish and shellfish" .)
