For a lighter version, you can use a little less bacon and swap out mascarpone for cottage cheese or ricotta. To make this dish totally veggie friendly, you can omit the bacon and use vegetarian Parmesan.
Method
Based on 4 servings, adjust as needed.
Step 1
Place a large frying pan over a medium heat. Add half the oil and the bacon and sauté for 2–3 minutes until golden. Transfer to a plate. Add the remaining 1 tsp of oil, the garlic and courgette to the pan. Fry for 3–5 minutes or until golden, then turn the heat to low and keep warm while you make the sauce.
Step 2
Put the mascarpone, Parmesan, mustard and lemon zest in a small saucepan and place over a low heat. Stir until smooth, then add the spinach. Allow it to defrost, stirring occasionally, until the spinach has wilted and the sauce is creamy.
Step 3
Meanwhile, cook the pasta shells in a large pan of boiling, salted water, according to the packet instructions.
Step 4
When the pasta is nearly cooked, increase the heat under the courgette pan and add the peas. Drain the pasta shells, reserving a cupful of the cooking water, and tip into the frying pan. Remove from the heat, spoon over the sauce with a good splash of pasta water and mix well. Sprinkle over the bacon. Season to taste and serve with a little lemon juice and grated Parmesan.
