Spinach Emergency, Please Help!

Just a little bit ago my sister walked in with a gargantuan bag of spinach leftover from work.

This picture was taken after we ate a bunch of spinach at dinner.

Now, I’m left wondering what the heck am I going to do with all this spinach?

I need your help!

Please tell me your favorite usage for spinach, preferably something that uses a lot of spinach!
