Complete slice and a half of Edam (7)

I believe the answer is:

rounded

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

'complete' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'slice and a half of edam' is the wordplay.
'slice' becomes 'round' (I have seen 'Slice of bread ' mean 'round' so perhaps 'slice' could also mean 'round').
'and' means one lot of letters go next to another.
'a half of' indicates taking half.
'edam' halved is 'ed'.
'round'+'ed'='ROUNDED'

Can you help me to learn more?

(Other definitions for rounded that I've seen before include "Plump" , "(Of the lips) pursed" , "full" , "Complete and balanced; made curved" , "Well-developed; balanced" .)

I've seen this clue in The Globe and Mail.
