If you're adding all 150g of noodles, 100g of cabbage is enough. Just add a little more soy sauce.
Cut the cabbage into bite-sized pieces.
Prepare perilla seed powder, minced garlic, and salt.
Add perilla oil to a pan and stir-fry the cabbage.
Once the cabbage begins to soften, add the perilla seed powder and minced garlic.
Season with salt and stir-fry a bit more.
Transfer to a plate and serve.
