Thanks to top amateur cook in Fiji, there's no end of delicious food (6)
I believe the answer is:
fajita
'cook in fiji there's no end of delicious food' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'thanks to top amateur' is the wordplay.
I cannot quite understand how this works, but
'thanks' could be 'ta' (UK informal version of 'thank you') and 'ta' is located in the answer.
'amateur' could be 'a' and 'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fajita that I've seen before include "Wrapped Mexican dish" , "Soft tortilla with filling and grated cheese" , "Cooked meat or vegetables served with a soft tortilla and grated cheese" , "Mexican meat strip" .)
