Cut the radish and kohlrabi into cubes. Cut the snack tomatoes into small pieces or puree them with a hand blender. Stir the curry paste into the coconut milk.
In a pan or saucepan that fits a lid, heat the coconut oil and let the onions and then the garlic be translucent. Add the kohlrabi cubes and put the lid on. Do the same with the radish cubes after 2 - 3 minutes. After another 2 - 3 minutes, fold in the coconut milk mixture and snack tomatoes. Turn the temperature down a lot and let it simmer with the lid closed until it is firm to the bite. Possibly salt on the plate.
