Ha - I just remembered, last year we had the family at our place instead of my usual parents', and we barbequed burgers! Basically because everyone likes burgers.
If it's just the two of you I'd definitely just make whatever's you guys' favourite. In our case, that would probably be either bbq steak or lamb with sides and lots of red wine!
Last year we hosted a brunch for my family. Deviled eggs, fruit and yogurt parfaits, smoked salmon and horseradish cream cheese toast, and an egg casserole. Cinnamon rolls for dessert. It was perfect and I plan to do it again this year!
