Blitzed together in less than five minutes, this cheat’s pesto uses cashews instead of pine nuts as a cheaper, easier-to-get-hold-of substitute. I promise no one will know the difference.

1. Wilt the nettle tops in a saucepan with 1tbsp water.
2. Blitz the wilted nettle tops in a food processor with the grated Parmesan, garlic cloves, cashew nuts, lemon rind, extra virgin olive oil and nutmeg.
3. Taste your emerald blend and add any extra oil, salt or pepper you think it needs.
4. Slather the pesto over slices of crusty white bread, top with cooked chicken pieces, add Parmesan shavings and drizzle with olive oil for the ultimate spring treat.
