Prepare the Noodles: Start by cooking your noodles according to the package instructions until they are perfectly al dente. Drain and set aside.
Sauté the Veggies: In a large skillet, heat sesame oil over medium heat. Add the broccoli and mixed vegetables. Sauté for about 5 minutes or until the veggies are tender yet still crisp.
Mix Everything Together: Add the cooked noodles to the skillet. Pour in the tomato sauce, soy sauce, and chili paste. Toss everything together well to ensure the noodles and veggies are evenly coated with the sauce.
Season to Taste: Season with salt and pepper to your liking, stirring frequently, and cook for another 2–3 minutes until everything is heated through.
Serve Hot: Transfer the spicy noodles to a serving dish and garnish with additional chili paste or sesame seeds if desired. Enjoy!
