Ingredients 

  • 1 tablespoon olive oil
  • 1 tablespoon unsalted butter
  • 3 medium leeks, white and light green parts only, sliced (about 3 cups)
  • 1 ½ lb (650 g) potatoes, peeled and cubed
  • 6 cups (1.5 l) vegetable stock
  • 2 cups (75 g) cavolo nero
  • ½ cup (25 g) fresh dill, roughly chopped
