Preheat the oven to 200'C and line a baking tray with baking paper. Set aside. Fill a large saucepan with salted water and add the potatoes. Place on a high heat and bring to the boil. Once boiling, cook potatoes for approx 15 minuted until tender.

Drain the potatoes and lay them out on the baking tray. Then, using the bottom of a mug, gently squash the potatoes. You want them flattened but still in one piece. Sprinkle with the salt, pepper, garlic powder and parmesan then drizzle with olive oil.

Bake the potatoes for 15-20 minutes until golden. Meanwhile in a bowl, mix the pesto and olive oil together. Remove the cooked potatoes from the oven and serve hot with the pesto drizzled on top or on the side for dipping.
