Preheat your oven to 180 degrees Celsius (350 degrees F).
Mix the curry powder, ground cumin, garam masala, ground coriander, salt and pepper together, then transfer half of that spice mix to a separate bowl.
Put your diced potatoes, curry sauce, and one half of your spice mix in a large bowl and mix together until well combined.
Lay the potatoes out over a baking tray, and then roast in the oven for 35 minutes.
Rub the other half of your spice mix over the pork chops.
Turn the heat off, then transfer the pork chops over the green beans and potatoes on the tray.
Cook in the oven for 10 -12 minutes.
