1In 10-inch skillet, heat all succotash ingredients over medium heat 4 to 6 minutes, stirring occasionally, until edamame are crisp-tender; refrigerate.
2In shallow glass or plastic dish or resealable food-storage plastic bag, mix all marinade ingredients. Add beef; stir to coat with marinade. Cover dish or seal bag; refrigerate at least 2 hours but no longer than 24 hours, stirring once, to marinate.
3Heat gas or charcoal grill. Drain beef, reserving marinade. On each of twelve 10-inch metal skewers, thread beef and onion alternately, leaving 1/4-inch space between each piece. Brush onion with reserved marinade.
4Place kabobs on grill. Cover grill; cook over medium heat 6 to 8 minutes for medium beef doneness, turning and brushing with reserved marinade occasionally. Discard any remaining marinade. Serve kabobs with succotash.
