Step 1 While the pasta is cooking, heat the oil in a large saucepan. Sauté the bacon until starting to brown, add the nuts and cook with the bacon until toasted. Add the garlic and spinach and toss gently until spinach wilts.

Step 2 Drain the pasta and add to the pan, tossing to coat the pasta in the bacon and spinach mixture. Add the zest and juice of the lemon, taste and adjust lemon accordingly. I like it quite zingy. Pile into bowls and finish with grated parmesan cheese.
