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

'very pleasant to eat' is the definition.
I can't tell whether this defines the answer.

'from rome his mash' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'mash' is an anagram indicator (letters mashed up).
'rome' with letters rearranged gives 'more'.
'his' anagrammed gives 'ish'.
'more'+'ish'='MOREISH'

Can you help me to learn more?

(Another definition for moreish that I've seen is " addictive".)

I've seen this clue in The Daily Express.
