Cook the rice noodles according to package instructions. Drain and set aside.
Heat vegetable oil in a large wok or skillet over medium-high heat. Add the broccoli, bell pepper, carrot, and zucchini. Stir-fry for 3-4 minutes until the vegetables are tender-crisp.
Add the minced garlic and grated ginger to the vegetables, stir-frying for an additional 1-2 minutes until fragrant.
In a small bowl, whisk together the soy sauce, hoisin sauce, rice vinegar, and sesame oil. Pour the sauce over the vegetables and toss to coat evenly.
Add the cooked rice noodles to the wok, tossing everything together until well combined and heated through.
Garnish with sliced green onions and sesame seeds before serving.
Notes
To save time, prep all your vegetables and have the sauce ready before you start cooking. Stir fries come together quickly, so it's best to have everything ready to go.
Cook the rice noodles until just al dente. They’ll soften a bit more when you toss them with the vegetables and sauce, so you don’t want them too soft from the start.
Stir-frying works best with high heat. It cooks the vegetables quickly while keeping them crisp and vibrant.
Feel free to tweak the sauce to your liking. If you prefer it a bit sweeter, add a touch more hoisin sauce. If you like it tangy, a splash more rice vinegar will do the trick.
If you want to add some (vegetarian) protein, tofu, tempeh, or even some edamame would be great options. Just stir-fry them before adding the vegetables.
