Recipe help!

We have an annual Christmas party with my friends from high school and our growing families. Sunday is this year's get-together and we're in charge of the meat dish.

So I need something to serve that will feed 11 adults (six women, five fellas with big appetites) and four children between the ages of 16 months and four years old.

I have two awesome recipes - one for an Italian Chicken Bake and one for Quesadilla Casserole (I'll post them later) - but here's the problem: we have allergies to tomatoes AND someone on a gluten-free diet. Which pretty much kills those two ideas.

I'd be grateful to all you cook-savvy bloggers, moms, and folks who just know their way around a kitchen better than I do if you sent me some suggestions.

Thanks!
