Begin by cooking the vermicelli noodles according to package instructions. Drain and set aside.
In a large skillet or wok, heat the vegetable oil over medium-high heat.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 30 seconds until fragrant.
Add the enoki mushrooms to the skillet, cooking for 2-3 minutes until they start to soften.
Stir in the soy sauce, oyster sauce, and sesame oil, mixing well to coat the mushrooms. Cook for an additional 2 minutes.
Toss the cooked vermicelli noodles into the skillet, mixing everything together until the noodles are heated through. Season with salt and pepper to taste.
Remove from heat and garnish with sliced green onions. Serve immediately with lime wedges on the side.
