Bring a saucepan of lightly salted water to the boil over a high heat. Add the pasta and cook according to the instructions on the packet, or until al dente. Drain and transfer to an ovenproof baking dish.
Into a saucepan combine the tomatoes and mascarpone cheese and warm over a medium heat. Add the Quorn® chicken and bacon and stir through; pour over the pasta and stir to mix. Sprinkle over the cheese and season to taste.
Bake in the preheated oven for 20 to 30 minutes until bubbling and the cheese is golden brown. Remove from the heat and serve.
