Cut the cabbage, enoki mushrooms, and onion into bite-sized pieces.
Heat some cooking oil in a pan and sauté the onions first.
When the onions become translucent, add the cabbage and stir-fry.
Once the cabbage softens, add the enoki mushrooms and stir-fry together.
Season with salt and pepper.
When all the ingredients are cooked through, turn off the heat and plate the dish.
