In a large wok or non-stick skillet, heat your sesame oil. (At the same time, prepare your boiling water for the pasta.) After a minute or 2, add all of your chopped vegetables and garlic into the wok or skillet and saute for a few minutes. Season with salt and continue tossing for a few minutes longer until the vegetables are tender but not too soft.
While you are cooking your vegetables, boil your linguine noodles as well. Cook to al dente, according to package directions (about 7-9 minutes). Drain and set aside.
When the vegetables and noodles are ready, add the noodles into the wok. Add the chicken broth, soy sauce and oyster sauce. Toss for a few minutes or until well combined. Taste and season with more soy sauce and/or oyster sauce as needed. Garnish with the green onions and serve immediately.
