Gently roll each skewer in the breadcrumbs and then the cornstarch. Place on a clean tray until ready to cook.Can be prepared one hour in advance.
COOKING
Heat oil in a large saute pan on medium-high heat. Saute skewers turning until browned on all sides and cooked through, 12-15 minutes.
SERVING

Notes
To make the skewers you need to know how to use fresh lemongrass stalks. First trim both ends cutting off about an inch of the hard root end then about one-third off the top of the stalk. Next remove the toughest outer pieces from the stalk, two or three pieces depending how thick the stalk is. Now you have the most tender part of the stalk to use. Cut the skewers to the size you want.
