I, personally, have no idea, and maybe an approximation would not be adequate for this, but that's the only thing i can offer

An American friend of mine who has lived with Koreans in America tells me that the would say:
a mhe li kan or
a mhe li ken (dipending on how similar to the English sound they want to do it). The "mhe" stays for a "me" with a slightly longer "e".
I cannot provide you a phonetic spelling, but i can tell you that these vowels would probably be more similar in pronunciation to the Italian or Spanish ones than to the English ones.
Unfortunately, nothing of this is for sure. I hope some Korean will see this thread and be able to give you a more accurate answer.
