Whisk together the fish sauce, vinegar, sesame oil, oyster sauce, and soy sauce in a small bowl. Set aside.
Cook the noodles according to package directions for al dente. Reserve 2 tablespoons of the cooking water before draining the noodles.
Return the cooked noodles to the pot and set the heat to medium. Pour the prepared sauce mixture into the pot along with the reserved cooking water. Toss well and cook, stirring occasionally, until the sauce clings to the noodles. Transfer to a serving bowl and top with the grilled vegetables. Garnish with chopped peanuts and sesame seeds.
Notes
To store your Veggie Noodle Bowls, place leftovers in an airtight container and refrigerate for up to 3 days. If the noodles and veggies are stored separately, it helps maintain texture. This dish doesn’t freeze well, as the noodles can become mushy.For reheating, warm the noodles and veggies in the microwave or on the stovetop over medium heat until heated through. Add fresh peanuts or toppings just before serving to preserve their crunch.
