Only 2 reviews in and already the rule book is out the window! Not that there is a world of difference between the modern sandwich and pizza, both being doughy arrangements existing to showcase the ingenuity, or lack thereof, of the additional ingredients. The Unified Review Theory overview of Christmas snacks is a broad church and does not discriminate against any as long as they contain turkey and stuffing.
It must have been an exciting moment in the Morrison’s food labs when they squared the circle of how to combine Christmas with pizzas. This they did by adding the key ingredients of a Christmas dinner, namely cooked turkey, stuffing, bacon, cranberry, cheddar cheese and tomato sauce, to a pizza base. The genius, you see, is in the simplicity. The finished article is maybe less than the sum of its parts, and those parts are fairly lacklustre to begin with, but you have to reward their demented genius.
Better still was the cheese board pizza, but that is a whole other review.
