What is not necessary to consider when you are planning meals for yourself?
foods you like
any allergies you may have
your available finances
none of the above

I'd say none of the above! If you're planning for yourself you'll want to choose foods you like. It's imperative that in planning meals for anyone you consider their allergies, you don't want to kill them! Your available finances are also important, if you can't afford to go to a fancy restaurant, don't!
