These are an adaptation of my cheesy veggie pasties and are a samosa / pasty hybrid.
Follow the cheesy veggie pasties recipe but add a teaspoon of curry powder and 2 tablespoons of sesame seeds to the pastry. For the filling add a couple of tablespoons of plain yoghurt, 2 tsp of curry powder, 1/2 tsp chilli powder, a tsp of toasted cumin seeds, and a handful of chopped coriander leaves (you can also swap the cheddar for a tub of cottage cheese and the butter beans for chickpeas or lentils if you like). Follow the instructions for the cheesy pasties. These go really well with mango chutney.
