Ingredients:

  • 2 tablespoons olive oil
  • 1 onion, sliced
  • 50g California walnuts, roughly chopped
  • 1 gherkin, finely diced
  • 1 tablespoon American yellow mustard
  • 1 tablespoon chopped parsley
  • 4 jumbo frankfurters
  • 4 hot dog rolls, split down the center

Preparation:

  1. Heat the oil in a frying pan and fry the onion for 5 -7 minutes, add the walnuts and fry for a further 1 minute. Transfer to a bowl and mix in the gherkin, mustard, 1 tablespoon water and parsley, season.
  2. Cook the frankfurters on a BBQ or griddle pan for 5-8 minutes, turning until evenly cooked. Serve in the buns topped with the walnut mustard relish.

Cook’s tip: Add tomato sauce to the buns before adding the frankfurters if liked. The relish can be made ahead and kept in the fridge until needed.
