We will be hosting a casual potluck at our home for 40-50 people in December and need to contribute a main dish. Our crock pot will be full of hot spiced cider. Everyone will contribute a dish, we don't use a list to assign dishes other than last name from A-M takes dessert otherwise take an appetizer or main dish, and somehow it all works out. :-)

Since this will be at our home, I don't want an expensive, complicated labor-intensive dish. Also, not too heavy or rich since there will be other food.

Ideas include:

Lasagna (make ahead)

Meatballs (make ahead) in good marinara (also make-ahead) -- but what to serve in?

Casserole -- not heavy and cream-ladened

This is also an opportunity to try something new but T&T, and would love some ideas.
