Preheat oven to 180c, fan setting.
Place all of the vegetables in a baking tray, along with the drained chickpeas and a good drizzle of olive oil, salt and pepper.
Give everything a really good mix, before placing in the oven for 35-40 minutes.
while the vegetables are cooking, place the tinned tomatoes, tomato puree, maple syrup, chilli flakes and another pinch of salt and pepper in a pan over a medium heat.
Bring to the boil, before reducing the temperature and leaving to simmer for 10-15 minutes.
place the coconut milk, tomatoes, turmeric, cumin and ground ginger in a large saucepan or even better a cast iron casserole dish, allow these to heat until they begin bubbling. at this point add the sweet potato cubes, lentils, plus salt and pepper.
once everything is mixed simply place the lid on the pot and place it in the oven to cook for 45 minutes to an hour, until the potatoes are soft and everything tastes delicious! at this point squeeze the lemon juice into the pot and then serve.
