Do you know abt Maangchi ? She has YouTube channel and shares Korean recipes . Her videos are so much fun. There are few vegetarian recipes there.
Most of the recipes I watched has onion, green onion , garlic, soy sauce, Korean chili powder, roasted sesame oil. Besides Korean chili powder I went and bought other things and sautéed vegetables. Simple recipe and takes few minutes only. No left over.
Enjoy!
