How to cook?

Ok~~ i'm home alone this weekend........instead of cooking instant noddle. I try to cook Spaghetti~~ which i never try before. Always see my ex-housemate cook it, but i never ever cook it~~

So i bought the most important ingredient. The pasta!!! and the sauce!!!! but what next?
minced beef? hotdog? onion?


End up, i forgot where my mom put the minced meet.......and my spaghetti is plain~~ totally pasta + sauce + hotdog~~~
Yiak~~~ disgusting~~
