Second helping covered by ham or eggs (4)

I believe the answer is:

'second helping' is the definition.

'covered by ham or eggs' is the wordplay.
'covered by' indicates the answer is hidden within the clue.
'MORE' is hidden in the letters of 'ham or eggs'.

(Other definitions for more that I've seen before include "A greater amount" , "What Oliver wanted" , "Greater quantity or number" , "See 9" , "author" .)

I've seen this clue in The Telegraph.
