It's better not to use noodles for pasta, but other small shapes can be used. Cook it at a certain temperature according to your taste and filter out the water?

Tips:

It doesn't matter if you don't have ketchup at home. You can divide the diced tomatoes into two parts, those with skin and those without skin. Stir-fry the onion without skin first, and it will basically be fried into mud. Finally, when you need to put tomatoes, just put the part with skin in.
