Our stir-fried udon noodles have unusual ingredients such as garlic and ketchup.
One day I had stir-fried udon from a food stall and I liked it because it had garlic. Since then we like garlic in our stir-fried noodles.
Green onions are easy to cook through. To keep their crunchiness, don't cook for too long. The white stem parts take longer to cook through so I recommend that you fry with cabbage beforehand.
