I made amazing Stuffed Shells Florentine the other night but the only thing is -- I've got quite a bit of fresh basil and thyme left over. I hate to let it sit and go to waste, but I'm not quite sure about what flavors/meats/etc go good with certain herbs.

I come across this problem a lot (of making something that requires a certain ingredient and then having leftovers that go bad.)

What do you do with your "leftovers?"
