Soak the dried glass noodles in warm water according to the package instructions to soften them before cooking.

Bring a large pot or wok of water to a boil over medium-high heat. Add the softened glass noodles and cook until just tender. Remove the noodles and set aside to drain.

Cook the pork in the same pot. Once done, remove using a fine mesh strainer and place it in a large mixing bowl. Add the noodles to the same bowl.

Add the fish sauce, white sugar, lime juice, pickled garlic water (if using), coriander, green onions, Chinese celery, chilies, onion, and tomatoes. Toss everything gently to combine.

Finish with roasted peanuts if using. Let the salad sit for a few minutes before serving so the flavors can soak in.
