I bake like there's no tomorrow, victoria sponges freeze really well as does shortcrust pastry and pasta dough. All easy and relatively quick and full of eggs, the dough can be frozen whole too.
I have tried freezing eggs, seperate eggs and put them in ice trays, with salt or sugar. The salt/sugar is to stop skin forming when you defrost. Got to admit I haven't tried defrosting them yet as we have never been short.
Pickling too, we do this a lot with quail eggs and sell them.
