We want something piquant on Boxing Day after all the richness of Christmas Day eating. I also don't want to spend too much time cooking. So, simply mix a jar of good tomato passata with a few tablespoons of double cream or creme fraiche. In a wide shallow dish, lay thick slices of leftover turkey, and stuffing if you have any. Add some frozen mixed peppers (or sauteed sliced fresh) and some sliced and sauteed mushrooms. Pour over the creamy passata, top with breadcrumbs mixed with grated parmesan, and drizzle with a little olive oil. Bake in a medium oven until the turkey is piping hot and the breadcrumbs are crisp and brown. Nice with some crusty bread, pasta or even leftover roasties, heated up again until crispy. Lots of green veg or salad seems essential too. Soup and Thai green curry with the remaining bird.
