Step 1

Pre-heat your oven to 220ºC and chop the potatoes into cubes. Finely chop the onion.

Step 2

Place the potatoes in a pan with water and parboil. They should be almost cooked through but still firm.

Step 3

Drain the potatoes, add the chopped onion and sprinkle over the garam masala, onion granules, garlic granules, ginger, chilli powder, coriander, cumin and lime juice. Toss to coat. Spray with low calorie cooking spray so that all the potatoes are coated.

Step 4

Spray a baking tray or oven proof dish with low calorie cooking spray and spread the potatoes over the tray.

Step 5

Put the potatoes into the middle of the hot oven for around 20 minutes, until the tops have coloured and look crispy. Flip the potatoes over and bake for a further 15 - 20 minutes.

Step 6

Remove the potatoes from the oven and stir in the spinach while they are still hot so it wilts.

Step 7

Season with salt and pepper to taste. An optional extra is to sprinkle over some fresh coriander before serving.
