Sautee half of the onions and garlic in 2 tablespoons oil over med-high heat until onions are semi-cooked. Add chicken and cook until done. Remove and set aside.
Meanwhile, put rice noodles into a large bowl of very warm water and let soak until limp, you may want to cut noodles in half with kitchen shears after soaking.
Saute the rest of the onions, celery, and carrots in 1 tablespoons oil for 1 minute. Add chicken broth, cabbage, soy sauce, and accent to the vegetable mixture. Add the chicken back in and add drained noodles. Stir mixture and cover pot and allow to cook for 10-15 min., stirring occasionally and checking liquid. You may add more broth if liquid boils out before the vegetables are tender.
Season with black pepper and serve immediately with lemon wedges on the side. This dish is very good with fresh lemon squeezed over it!
This can also be made with just vegetables, for a vegetarian version, or with shrimp, pork, beef, or a mixture of all.
