I agree. You haven't had a real breakfast until you've had a "Full English" one. The classic British Roast Dinners with Yorkshire Pudding are fantastic too as are some of the British pies. I'm married to a Brit. I know.
For Christmas dinner we always had roast beef, homemade Yorkshire pudding, and homemade plum pudding soaked in brandy (and ignited) for dessert.
Why this I never understood as there were no English people in my family tree. My father's side was German and my mother's side was Swedish.
We had a Swedish smorgasbord (julbord) on Christmas Eve, with all kinds of great treats, including homemade meatballs and sausage, coldcuts, hardtack, pickled herring, cheeses, lingonberry jam (much better than cranberries), and the like.
Of course, there is also ‘Stargazy Pie’:
