Pizza-style penne with salami crisps

Method

1. Cook the penne in a large pan of salted boiling water according to the packet instructions, then drain, reserving a cupful of cooking water.
2. Heat 1 tbsp of the oil in a large pan over a medium-high heat and fry the 4 salami slices for 2-3 minutes until crisp, then transfer to a plate.
3. Add the remaining oil to the pan and fry the onion for 7-8 minutes until softening, then add the garlic, capers and anchovies for another minute. Tip in the tomatoes and chicken stock, season well and simmer for 15 minutes, then stir in the mascarpone. Season well and whizz with a stick blender until
   smooth (or leave it chunky if you like).
4. Add the pasta to the sauce along with a splash of the pasta water and
   the salami, then stir until well coated. Stir in the basil and serve with the mozzarella and broken salami crisps, with extra basil.
