What baked pasta dishes can I make for a birthday party?

I'm having family over to celebrate me son's birthday. We are having lunch, 'll need enough for 10-12 people. Originally I was going to go with finger foods. Tea sandwiches, chicken salad, fruit and veggie trays... Now I'm thinking it might me easier to do a couple baked pasta dishes. I have no idea what to fix. I want to make two different choices. I don't really want to do baked spaghetti or anything with canned Alfredo (I think it taste weird) anything else I'm willing to try, any ideas??
