Soak or boil 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 minced garlic and chilies; stir-fry until fragrant, about 30 seconds.
Add onion, bell pepper, broccoli, baby corn, and carrots. Stir-fry for 2-3 minutes.
Push veggies to the side and add chicken or tofu. Cook until fully cooked through.
In a small bowl, mix soy sauce, oyster sauce, fish sauce, dark soy sauce, sugar, and water.
Pour sauce into the wok and mix everything together.
Add the noodles and toss to coat in the sauce evenly.
Turn off the heat and fold in Thai basil leaves until wilted.
Serve hot and enjoy immediately.
