I recently picked up the Moosewood Cooks for a Crowd cookbook, which has a bunch of vegetarian recipes that they claim feed about 20-24. The ones I've tried feed freeze really well, and are quite tasty.

I think Chapters/Indigo currently has that going for about 5$ (which is where I picked up my copy) - you might want to check it out, if you're interested in recipes in fairly massive quantities.

(Also, can I express a serious amount of jealous with regards to your freezer? Really now. Jealousy. I'm turning green as I type.)
