Ingredients

Preheat the oven at 200C degree. Line the baking sheet with parchment paper. Slice the potatoes and with a sharp knife cut vertical and horizontal narrow lines on each slice of potato as you see in the photos.

Season with salt and pepper and place them on the baking sheet. Spray oil on potato slices and allow to roast for 15 minutes.

While potatoes are in the oven, prepare the sauce: in a bowl add 1tbsp oil, tomato paste, tomato ketchup, oregano, salt and pepper. Mix together.

Remove potato tray from the oven. Add enough sauce mix to cover top of potatoes.

Sprinkle on the grated cheese, followed by chopped bell pepper, olive and salami.

Cook the pizza in the oven for next 10-15 minutes or until cheese is melted and serve them.
