Stuff? Kosher isn't "stuff", moron. Also, you avoid kosher foods by knowing kashrut law and breaking it. Like if you get handed a hebrew national hotdog, slather it in cheese. It is against kashrut law to mix meat and dairy, so your hot dog is no longer kosher.
However, f a non-Jew prepares food, it cannot be kosher. So, provided you're not a kike, if you make the food, it's never going to be kosher - even if the package was certified kosher.
