First, boil water. Put glass noodle on a deep dish and pour enough boiling water to cover the noodles. Set aside.
Meanwhile, heat a pan over medium high heat.
Add sesame oil when pan is hot then saute garlic, onion and chicken or pork. (If you want to add mushroom, add at this step.)
Add chili flakes, season lightly with soy sauce (or salt) and ground black pepper.
Pour the chicken or pork broth or water. Bring to a boil
Add soaked glass noodles, parsley leaves.
Stir to mix then add cabbage and other veggies you might want to add . Add mung bean sprout at this stage, if using
Stir and cook until the liquid is absorbed. Taste adjust seasoning if necessary.
As a last step, I like to drizzle some sesame oil just before turning off the heat.
Give a quick stir again and divide into individual serving bowls.
