Ingredients
  • 2 pouches Merchant Gourmet Tomatoey French Puy & Green Lentils
  • 1 red onion, thinly sliced
  • 1 bag spinach
  • Pinch of sugar
  • Olive oil
  • Herby Oil
  • Handful fresh basil
  • Handful fresh parsley
  • Handful fresh coriander
  • 4 tbsp olive oil
  • ½ lemon, juiced

  1. Preheat the oven to 180°C.
  2. Heat a drizzle of olive oil in a frying pan over a low heat. Add the red onion and sugar and cook gently for around 15 minutes until soft, golden and caramelised.
  3. Meanwhile, make the herby oil. Finely chop the basil, parsley and coriander and mix with the olive oil, lemon juice, salt and pepper. Set aside.
  4. Add the spinach to the onions and cook until wilted.
  5. Stir through the Merchant Gourmet Tomatoey French Lentils and warm through.
  6. Line the base of an ovenproof dish with a circle of baking parchment.
  7. Lay 2 sheets of filo across the dish, allowing the edges to overhang. Brush generously with melted butter.
  8. Lay another 2 sheets crossways over the top and brush again with butter. Repeat until you have built up several layers.
  9. Spoon the lentil filling into the pastry case.
  10. Dot over teaspoons of N'duja and scatter over the feta.
  11. Add the tomatoes and fold the overhanging filo edges towards the centre.
  12. Brush the pastry generously with more melted butter.
  13. Bake for 30 minutes until crisp and golden.
  14. Finish with the herby oil and serve with a fresh salad or crushed new potatoes.
