Boil medium sized potatoes in their peel for 40 – 50 min. Cook the veggies you want to add to the potato later for about 20min. Take the potatoes and cut them in half (not completely down, as you want them to stay together). Take some of the potato out with a spoon and start filling the 2 halfs up with the veggies. Add a mixed egg (if you want to keep it dairyfree) or Mozzarella on top. Spice it up with some salt and pepper. Put it in a preheated oven at 180C for around 20min. Enjoy!
