Stir-fried Beef, Vegetable, and Tofu Noodles

Cut the beef, tofu, and vegetables into bite-sized pieces.

Add cooking oil to a pan and stir-fry the beef.

When the beef is about halfway cooked, add the vegetables and tofu, and stir-fry together.

Season with salt and pepper to taste.

Once all the ingredients are cooked, transfer to a plate and serve.
