Cook Christmas dinner for five people for under €25

My niece was born on Christmas Day. I know this because it was the first time I cooked Christmas dinner and her arrival (at slightly more than half the weight of the turkey) rather stole the show. It also stole most of the dinner guests and when we finally sat down it was just my mother, my younger sister and her boyfriend visiting from Germany. There was enough food to feed the German army and Fritz thought we were savages. He told me as I carved the turkey that he was, in general, vegetarian. Not today buddy, not today.
My niece will be 21 this Christmas day, Fritz is long gone, and I have learned a lot about cooking Christmas dinner. In the meantime I have also become parsimonious and hate wasting food or money. I take pride in cooking the best food for my family for as little money as possible. I wade through the supermarket hype of loyalty cards and bonus points and two for one offers to find what really is good value and what is a load of horseradish. And Christmas is surely the most confusing time of all. Well relax, pour yourself a sherry, turn up ‘Oh Holy Night’ and I’m going to tell you how to cook a traditional Christmas dinner for 5 people for slightly under €25.
