Thinly slice the onion. Cut the bell pepper and carrot into thin strips. Slice the cabbage into 1/2-inch (1 cm) wide pieces. Cut the pork into bite-sized pieces.

Heat vegetable oil in a frying pan and add the pork. Stir-fry until it starts to change color.

Add the vegetables and stir-fry together.

Once the vegetables are cooked, add the udon noodles. Add the soup mix and water, stir to coat everything evenly, and cook until heated through. Serve in a bowl and top with bonito flakes.

These are the ingredients I used.
