Pre-heat the oven to 200°C.
Take a wrap and spread the tomato puree and cranberry sauce over it, leaving a 1cm gap around the edge.
Lay the sliced turkey and brie over half of the wrap, making sure to leave the 1cm gap free. Season with salt and pepper to taste.
Brush beaten egg around the edge of the wrap on the gap.
Fold the wrap in half and press down around the edge. Crimp the edges using the back of a fork, then place on a baking tray sprayed with low calorie cooking spray. Brush the outside of the calzone with beaten egg.
Bake at 200°C for 10 to 15 minutes or until golden brown.
