  • 50 g hard cheese, such as cheddar, parmesan, gruyere, chopped
  • 1 cloves garlic
  • 2-3 tbsp olive oil

For the fish cakes

  • 100 g leftover mashed potatoes
  • 1 handfuls leftover broccoli, roughly chopped

1. For the pesto: tip all of the pesto ingredients into a food processor and blend to a rough paste. Set aside.

3. Roll the fish cakes in the flour, dusting off any excess, then dip in the egg and lastly the breadcrumbs, to coat completely.

4. Heat 1cm of oil in a frying pan over a medium heat and fry the fish cakes for 4-5 minutes on each side, or until crisp and golden and heated through.

5. Serve the fish cakes with the pesto.
