Cook the spaghetti in boiling salted water according to the packet instructions. Prepare your sauce by gently heating a little olive oil then add the garlic, chilli, and anchovies. Add the wild rocket, toss and add the lemon zest. Remove from the heat and add the lemon juice.
Drain the spaghetti then toss it with the sauce, taste and season if needed. Place on a plate and pile the extra handful of wild rocket on top with a good sprinkling of grated Parmesan.
