Tip the potatoes, pasta and stock into a flameproof casserole. Bring to the boil over a medium heat, then reduce the heat to a simmer and cook for 15 mins uncovered and stirring occasionally. Stir in the pesto, green beans, lemon zest and some seasoning, and cook for 2 mins more.
Cover the pot with a lid, remove from the heat and leave to stand for 5 mins. Serve the pasta in bowls, topped with grated cheese.
