Begin by prepping the Enoki mushrooms. Trim off the ends and separate them into small clusters.
In a large skillet heat 1 tablespoon of oil over medium-high heat. When the oil is hot, add in the Enoki mushrooms and cook for 3-4 minutes until they start to turn golden brown. Flip them over and continue cooking until all sides have been cooked through.
In a small bowl mix together the gochujang, sugar, soy sauce, rice vinegar, toasted sesame oil, and water.
Add 1 tablespoon of oil to the skillet along with the garlic and gochugaru (optional). Cook for about 30 seconds until fragrant.
Pour in the sauce mixture and give it a quick stir. Add in the Samyang Buldak sauce (optional) and cook for another 2-3 minutes until the sauce thickens.
Add the Enoki mushrooms back into the skillet and give it a good stir to coat them with the sauce. Cook for 2-3 more minutes until everything is heated through.
Serve immediately over steamed rice or noodles!
