게 잘리다

get cut, come already cut

잘리다 is the passive of 자르다 — the thing gets cut rather than someone cutting it — and the "-게" adverb says how it turned out: 예쁘게 neatly, 수월하게 easily, 잘게 finely, 요상하게 oddly. Most lines are food already prepared: it's cut into pieces, cut small enough to eat easily, it cuts much more easily after the microwave. It also covers a body part being cut off, and a haircut. 잘리다 is also the word for being fired, though none of these lines use it that way.
