Cook the potatoes in boiling, salted water for 10 minutes. Drain, then roughly mash them.

Heat a large pan to medium, and saute the onion and garlic in the oil until soft. Stir the onion, garlic, grated carrot and kale into the potatoes. Add seasonings, adjusting to taste.

Shape the mixture into 9 small rounds, and put them on a lined baking tray. Bake at 350 degrees F for 25-30 minutes.

If you prefer to fry your burgers, heat a pan, add a teaspoon of oil and lay the patties in the pan. Let them cook for 7-10 minutes before flipping and cooking for another 5 minutes or so on the other side.

To finish them off, you can top them with a slice of tomato, sprinkle with salt and pepper, and put in the oven on broil for 2-3 minutes.
