Par boil the potatoes in a pan. I usually add them in boiling water speeds up the process. Also take the skin off before boiling.

After they are boiled chop them in halves and place them in a oven tray then add olive oil to cover the potatoes in then add salt pepper and chilli flakes then sprinkle the semolina then bake in the oven at 200 degrees until they are golden and crispy. Enjoy with your meal....
