Cook the rice noodles according to package instructions to cook the noodles, strain the water, then set aside until ready to use.
Heat oil in a wok over medium heat. Add the garlic, broccoli, and carrots and saute, stirring occasionally, until vegetables begin to soften, about 3 to 5 minutes.
Add the zucchini and continue cooking until vegetables reach desired done-ness.
While the vegetables are cooking, scramble up the eggs in a separate small skillet.
Transfer the noodles to the wok, along with the remaining ingredients. Cook until the liquid burns off and noodles begin to caramelize, about 8 to 10 minutes. Taste noodles for flavor and add more fish sauce and/or coconut aminos to taste.
Stir in the scrambled eggs. Serve stir fry noodles with chopped green onion and sesame seeds.
