Heat 1/2 cup oil on medium-high in wok or large skillet. Cook chicken until done, turning often. Don't let it brown. Add celery and onion; stir constantly until onion is slightly glassy. Add bean sprouts (3/4 cup or to taste) and Chinese pea pods if desired and cook about 3 minutes more.

Just before serving, add about 1 1/2-2 cups peanuts. Takes 10-15 minutes to cook. Add more veggies if desired.
