Devours tuna melts, keen to try something unusual? (11)

I believe the answer is:

adventurous

I'm a little stuck... Click here to teach me more about this clue!

'keen to try something unusual?' is the definition.
I can't judge whether this definition defines the answer.

'devours tuna melts' is the wordplay.
'melts' indicates an anagram.
'devours'+'tuna'='devourstuna'
'devourstuna' with letters rearranged gives 'ADVENTUROUS'.

Can you help me to learn more?

(Other definitions for adventurous that I've seen before include "Taking risks" , "Daring" , "Dare-devil" , "Boldly enterprising" .)

I've seen this clue in The Independent.
