Plenty of joints do the porchetta-plus-salsa verde combo, so what is it about the Vancouver sandwich shop’s first Seattle outpost that serves up this combo with such satisfying success, it sells out daily? In a word, cracklings. The helpful servers slice off pieces of impossibly moist porchetta, pile it high on sturdy rectangular buns with the green sauce, then add in all that crackly fat that brings the lushness and the music. Just wow.
