'continental bread' is the definition.
'euro' can be an answer for 'bread' (I've seen this before). I'm not certain of the 'continental' bit.

'regret turning over' is the wordplay.
'regret' becomes 'rue' (to rue something is to regret it).
'turning' is a reversal indicator.
'over' becomes 'o' (cricket abbreviation).
'rue' in reverse letter order is 'eur'.
'eur'+'o'='EURO'

Can you help me to learn more?

(Other definitions for euro that I've seen before include "EU money" , "French currency" , "Common currency unit" , "Continental currency" , "Major currency" .)
