We’re always being told to eat more nuts, and walnuts are especially good for you. They’re high in omega-3 and cancer-fighting antioxidants.
To make this walnut pesto, blitz the parsley, garlic, walnuts and pine nuts in a food processor.
With the food processor motor still running, pour in the extra virgin olive oil.
Season with salt and pepper to taste and stir in the grated Parmesan.
Toss with cooked pasta. Leftover pesto can be drizzled onto a pizza, stirred through soup or spread in a chicken sandwich.
