Put the Puy lentils, garlic, red onion, carrots, mixed spice, cumin, coriander, chilli, ginger, leek, stock and carrot juice in a large pan. Bring to the boil and simmer for 25 minutes until the lentils have absorbed the stock and carrot juice.
Stir in the Spring greens for 3-4 minutes stirring continuously then add the apricots and the coriander and stir to mix. Use a Pyrex dish or tine about 27x18 cm and put a couple of sheets of filo pastry on the bottom of one half of the tin, then another two sheets on the bottom of the other side of the tin. Let the extra filo pastry hang over the edges. You'll tuck them in a bit later on.
Add the lentil mixture to the Pyrex dish/tin and fold over the filo pastry. Add another couple of sheets of pastry over the top, score diamonds into the pastry with a sharp knife and then brush with rice or almond milk then sprinkle with the sesame seeds.
Bake in a preheated over for about 35-40 minutes until the pastry is golden brown.
Serve with baby new potatoes, tender stem broccoli and cavolo nero.
