Prepare the Sauce:
In a medium bowl, mix oyster sauce, soy sauce, dark soy sauce, fish sauce, sugar, and chili paste. Stir well and set aside.
Cook the Protein:
Heat 1 tablespoon of vegetable oil in a wok or large skillet over medium-high heat.
Add the chicken, shrimp, or tofu, and stir-fry until cooked through. Remove from the pan and set aside.
Stir-Fry the Vegetables:
Add the remaining tablespoon of oil to the pan. Sauté the garlic and Thai chilies for 30 seconds until fragrant.
Toss in the onion, bell pepper, and broccoli. Stir-fry for 2–3 minutes until slightly softened.
Combine and Cook:
Return the cooked protein to the pan. Add the soaked rice noodles and the prepared sauce. Toss everything together to coat evenly.
Cook for 2–3 minutes, allowing the sauce to absorb into the noodles.
Add Thai Basil:
Turn off the heat and stir in the Thai basil leaves. The residual heat will wilt them perfectly.
Serve:
Transfer the Drunken Noodles to a serving plate. Garnish with extra Thai basil or a lime wedge if desired. Serve hot.
