I would do an experiment and melt some, drizzling on a toasted english muffin, just to make sure they are still OK.
If they are, in fact, OK, start looking for cookie recipes that call for them to be dipped in melted chocolate. Peanut butter balls and filbert (hazelnut) fingers from the Company's Coming cookie book come to mind right off the top of my head.
You could also do a chocolate fondue - mixing the milk and dark chocolate or having them individually.
Add drizzled chocolate to any cookies you bake. It would be good on shortbread and my gingerbread recipe calls for some cocoa so I don't see why you couldn't drizzle those, too. Chocolate drizzled on top of rice crispie squares is good, too. Make a banana loaf and drizzle some chocolate on top.
Break the pieces up with a hammer and make chocolate chunk cookies instead of chocolate chip cookies.
Make some 'bark' - melted chocolate and other ingredients with almonds or other nuts.
ETA: Sorry - got a little carried away there. Just picture me as Homer with my tongue hanging out and drooling. Hmmmm... chocolate.
