Baked Spinach-Parmesan Dip

This was very good. I served it at a Superbowl party I hosted where we had way too much food and people still ate it even though they were totally stuffed. I got lots of compliments. I only used half an onion instead of whole one and a lot of people commented about how "oniony" it was, so I think I'll stick with halfing the onion from now on. I will definitely try adding artichokes next time and see if that makes it even better.
