I'm making him one of his favorite soups, Maryland style cream of crab soup. We fell in love with this soup when we visited my sister in Maryland several years ago for her wedding. It's especially wonderful due to the sherry. Crab and cream is great, but it's the sherry that's the kicker.
I'm also serving some sort of pie - whatever looks good at Costco the day I go shopping. We're leaving the next day for a long camping trip, so I don't have time to make anything since I'm preparing for the trip.
