Eccentric rues eating bagel and French bread (5)
I believe the answer is:
euros
'french bread' is the definition.
(I've seen this in another clue)
'eccentric rues eating bagel' is the wordplay.
'eccentric' indicates anagramming the letters.
'eating' indicates putting letters inside.
'bagel' becomes 'O' (circular).
'rues' is an anagram of 'eurs'.
'eurs' placed around 'o' is 'EUROS'.
'and' is the link.
(Other definitions for euros that I've seen before include "Monetary units" , "Rouse (anag.)" , "Continental coins" , "money" , "EU currency" .)
