One sweet potato (or if you prefer yams, they work great too)
1/4 cup Olive oil or Avocado oil
Sea salt
Preheat oven to 400F. Chop up the sweet potato into small cubes (~2-3cm cubed) into a bowl. Drizzle oil and mix well. Spread out on a cookie tray and sprinkle with sea salt to taste. Place in oven for about 20 mins. Take out and flip potatoes. Place back in oven for another 20-30 mins as per your desired softness.
