Carbonara with bacon, beans & courgette

Bring a large pan of water to the boil. Add the spaghetti and simmer for 5 minutes, then add the beans (or peas) and simmer for 3 more minutes. Scoop out a mugful of the cooking water, then drain the pasta and beans and set aside.

Meanwhile, heat the oil in a large non-stick frying pan over a medium-high heat and fry the courgette and garlic for 3-4 minutes until just golden. Tip onto a plate and discard the garlic. Return the pan to the heat with the bacon; fry for 4-5 minutes until golden. In a bowl, use a fork to mix the egg yolk, cheese and cream; add a good grinding of black pepper.

Tip the drained pasta and beans into the bacon pan and toss together. Take the pan off the heat, add 6-8 tbsp of the pasta cooking water and the yolk-cheese mixture. Stir everything until combined. Add the courgette and lemon juice and serve immediately.
