What do you do with your kitchen scraps?

When I cook, I like to prepare all the ingredients way before cooking time... just in case the little one decides to be cranky just then.  Whenever I have the time (i.e. the little one is taking a nap), I wash and chop everything up, then place them in the fridge for later.  Here's something all nicely prepared:

Notice that the vegetable scraps are in a box?  Why?  Because I collect them and freeze them.  What do you think I'll do with them next?
