Tacos produced on the Spanish shore (5)
I believe the answer is:
costa
'the spanish shore' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'tacos produced' is the wordplay.
'produced' indicates an anagram.
'tacos' anagrammed gives 'COSTA'.
'on' is the link.
Can you help me to learn more?
(Other definitions for costa that I've seen before include "part taken from man, originally" , "resort abroad" , "Rib (Botany, Zoology)" , "A Spanish coast like Del Sol" , "__ Brava, region of northeast Spain" .)
