Swiss Chard

It's in the bottom left corner of the box.. that was months ago.  It is now 2-3 times that size.  And I have another block that is just as big

No DIY today... at least not from me...  I need some help! 
I have Swiss Chard growing like CRAZY in my garden... with one problem......
What do I do with the stuff???
I tried cooking it like turnip greens/spinach but it ended up having a dirtish taste.. (not a member of the raw foods movement..) I had rinsed it off before hand. 
Do ya'll have any recipies or anything on how to use the stuff?
Every tried canning it or dehydrating it?  Does it work?

Help a girl out!
