Preheat the oven to 200C - 390F.
Wash, peel and cut the potatoes in half. Rinse the cut potatoes with water.
Add the potatoes to the skewers. Brush them with olive oil on all sides and leave a little bit of the oil to add at the end. Sprinkle the seasonings on top of the potatoes then drizzle the remaining olive oil on top.
Transfer the potato kabobs to a baking tray lined on parchment paper and bake for 30-40 minutes.
Bake for 20 minutes on one side and then turn them around for 15-20 minutes on the other side.
To make the sauce in a bowl, combine the mayonnaise, greek yogurt, and seasonings - whisk everything together.
Once the potatoes are baked, take them out of the oven and leave them to cool down for a couple of minutes.
