Feeding a large group

I'm trying to keep track of what I've been making for dinners since we started a community group with our church. We meet once a week and provide the main dish. Others bring side dishes, drinks, and sometimes dessert.

In no particular order:

Texas Chicken Enchiladas
Pasta with classic pesto (love the classic pesto recipe in The New Best Recipe... I use walnuts instead of pine nuts)
Pasta with homemade spaghetti sauce (tomato-meat sauce)
Breakfast for dinner (my favorite!--we do it once a month)--I mostly make egg casseroles, but I want to do french toast casserole too
Ham and potato soup
Appetizers for dinner (I made two appetizers--deviled eggs and spinach-artichoke dip--and every else brought one)

We have yet to try:

Chili
Lasagna
Lentil and sausage soup/stew
