-건 말건 pairs a verb with 말다 'not do it', covering both options and then brushing the difference aside: 그러건 말건 'whether he does or not, never mind', 준비가 되었건 말건 'ready or not', 비판이 있건 말건 'criticism or no criticism'. It always signals the speaker is going ahead anyway. Two of the example lines are false matches — 비건 there is the loanword 'vegan' (비건 마요, 비건 마라 소스).
