Over the years, our menu has developed so many 'must-haves' that it doesn't change much any more, especially with my daughters being grown. They want the 'tradition'. So we will certainly be having deviled eggs, lamb with two peppers which DH will cook on the grill, Crunchy Pea Salad (from Claire in Rescue many, many years ago), and Savoy cake for dessert among other things. The SIL to be loves blueberries, so the second dessert will probably be Charlie's No-Bake Blueberry Cheesecake.
Luckily we all love lamb. It's so expensive now that it almost has to be a holiday meal.
