This very easy side-dish recipe is inspired by the vegetables they give you at Teppanyaki restaurants. Teppanyaki is a style of Japanese BBQ where the cooking is done on a very hot grill at the table. Quite delicious! This recipe is extremely good when done on a hotplate on an outdoor bbq. For best results indoors, use a griddle or heavy iron skillet over a very hot heat. Perfect when served with rice and teriyaki meats. This recipe serves 2 large helpings, or 4 side helpings.
