I love chewy foods...the chewier the better...my favorites are:
teriyaki beef jerky
vegetarian beef jerky
grilled chicken er, gizzards? (korean dakdongjip)
pho w/ tendon
jjolmyun (korean noodles)
now and laters candy
i also love gnawing on the cartilage from chicken wings, though i'm not sure that quite qualifies as 'chewy'
so what are your favorite chewy foods?
