Highlands resident cooked bangers and legumes occasionally (8,5)

I believe the answer is:

aberdeen angus

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

'highlands resident' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'cooked bangers and legumes occasionally' is the wordplay.
'cooked' indicates an anagram.
'occasionally' means one should take alternating letters.
The alternate letters of 'legumes' are 'eue'.
'bangers'+'and'+'eue'='bangersandeue'
'bangersandeue' anagrammed gives 'ABERDEEN ANGUS'.

Can you help me to learn more?
