Even vegan can dine at home (3,2)
I believe the answer is:
eat in
'dine at home' is the definition.
(I've seen this in another clue)
'even vegan can' is the wordplay.
'even' indicates alternate letters (letters in even-numbered positions are used).
'can' becomes 'tin' (both are metal containers).
The alternate letters of 'vegan' are 'ea'.
'ea'+'tin'='EAT IN'
(Other definitions for eat in that I've seen before include "Dine at home" , "Avoid restaurant" , "get takeaway?" , "Stay at home for meal" , "Perhaps lunch at home" .)
