I think this is a great idea that you're doing!
So here are my suggestions: For an appetizer, you can try Baked Stuffed Avocado and Sweet Sour Meatballs. For a main course, try the Grill Greek Lamb Platter. It is absolutely delicious! And for dessert, try the Double Dark Fudge Brownie Cake.
Just writing up this yummy meal is making me hungry! 
Enjoy!
