Prepare the squash, scooping out the seeds and discarding them, cutting the rest of the squash into 2cm thick strips, halving down the middle lengthways.
Transfer to a bowl, coat well with oil and mix through the garam masala, salt and ground black pepper. Spread out on a couple of baking sheets and place in the centre of the pre-heated oven.
Bake for 30-40 minutes until the squash is cooked. Resist eating a whole tray and move on to making the rest of the curry.
Heat 2 tablespoons of oil in a large lidded frying pan, over a medium heat.
When the oil is hot add the mustard seeds and fry until they start to pop, add the chillies and onion.
Fry for around 12 minutes, the onion will be soft and golden, then add the garlic. Fry for a couple of minutes.
Add the beans, stirring to mix, followed by the tomatoes. Cook for a few minutes until the tomatoes have gone jammy around the edges.
Add the turmeric, ⅓ teaspoon of black pepper, ½ teaspoon of salt and the coconut milk.
Tip the squash into the mixture and stir it all to combine.
Cover and leave to heat for about 5 minutes, then check for seasoning and chilli heat.
