Ingredients

1 tbsp olive oil
1 medium red onion (100g), finely chopped
1 medium carrot (75g), peeled and grated
1 clove garlic, crushed
150g/5 1/2 oz green lentils, rinsed
1 x 400g tin chopped tomatoes
350ml/12 fl oz vegetable stock
150ml/5 1/2 fl oz water
2 tbsp tomato puree
1 tbsp soy sauce
4 tsp brown sugar
5 tbsp frozen peas (optional)

750g potato, peeled and cubed
20g/3/4  oz butter
4 tbsp milk

1 egg, lightly beaten

Method:

Heat the oil in a large saucepan and sauté the onion and carrot for 8-10 minutes stirring occasionally until soft and starting to brown. Add the garlic and cook 1 minute then stir in the lentils, tomatoes, stock, water, tomato puree, soy sauce and sugar. Bring to a boil, reduce the heat and simmer for 40-45 minutes, until the lentils are soft (older lentils will take a little longer). Add a little extra water if the pan gets too dry.

Meanwhile, boil the potatoes in plenty of salted water for around 15 minutes, until just tender. Drain the potatoes then mash well. Beat in the butter and milk and season to taste with salt and pepper.

Season the lentils to taste with pepper then divide them between small baking dishes or ramekins. I used 6 ramekin dishes 9cm diameter and 4 cm depth.  Spread the mashed potato over the lentils and mark in ridges with a fork. Refrigerate until needed.

Preheat the oven to 200c/400G/Gas 6/ Fan 180c. Put the pies on a baking sheet, brush the tops with the beaten egg and bake for 25-30 minutes, until the potato is golden on top and the pie is piping hot. Cool slightly and check temperature before serving.

Pies can be wrapped in clingfilm and frozen. Defrost overnight in fridge.
