Butternut Squash, chickpea and spinach curry

I found this recipe on a food blog called http://eatlikeagirl.com. A combination of a vegetarian friend coming for tea and a lone butternut squash sitting on my kitchen work bench for the last few days led me to the recipe. A very tasty meal which I made earlier in the day and just heated up. I think it may taste even better tomorrow.

Ingredients
Serves 4
1 butternut squash, 6-8 inches high, peeled and diced with seeds scooped out
200g spinach, washed and excess water squeezed out, chopped
1 tin chickpeas
1 tin tomatoes
1 tin coconut milk
2 cloves garlic, finely chopped
1 onion, finely chopped
1 green chilli, finely chopped. More if you like it very hot!
thumb size amount of ginger, peeled and finely chopped
A handful of chopped fresh coriander
Half a lemon

Spices:
1 tbsp cumin seed
1 tbsp coriander seed
1/2 tbsp turmeric
8 black peppercorns

Method
Grind the spices in a pestle & mortar.
Fry the onion until translucent over a medium heat in some oil (sunflower or groundnut). Add the garlic, ginger and chilli for a minute or so. Add the spices for a minute or so, you’ll start to smell them as they temper. Add the butternut squash and coat in the ingredients in the pan. Cook for a couple of minutes.
Add the tomatoes and coconut milk, and cook for 10-15 minutes (mine took a lot longer) until the squash is cooked and you can push a fork through it.
Drain the chickpeas and add to the sauce. Also add the spinach.
When the spinach is wilted and the chickpeas are warmed through, add the coriander and a squeeze of lemon juice. The lemon juice lifts the flavour nicely, taste as you go.
Salt to taste and serve with rice and/or flatbreads.
