Heat some oil in a pan and sauté the chopped onion until slightly golden. Add the ground beef and minced garlic, and stir-fry over medium heat until the meat changes color.

Add the ketchup, rice wine, and sugar, and stir-fry. Then add some water and simmer. Meanwhile, boil water in another pot, add salt and some oil, and cook the spaghetti.

While simmering the beef, you can add your favorite ingredients. This time, I added red bell pepper to simmer together. Once the flavors are absorbed, adjust the seasoning with salt, sprinkle with seasoning powder, and then add the cooked spaghetti to the pan and stir-fry together.

Once the sauce reaches your desired thickness, remove from heat. Sprinkle with more seasoning powder and black pepper, and enjoy.
