Step 1

Cut the potatoes into small cubes (about 1/2-inch), put them in a large pot, and cover with water. Bring to a boil and cook until potatoes are tender.

Step 2

While the potatoes are cooking, remove the center stalk from the kale and slice the leaves into strips. When the potatoes are done, lift them out with a slotted spoon and place in a large mixing bowl. Put the kale into the potato water and cook for 6 minutes or until kale is tender. Remove kale with a slotted spoon to a food processor. Add 1/4 cup of the cooking liquid and pulse to chop fine.

Step 3

Preheat oven to 425 F. Mash the potatoes and add the kale and all remaining ingredients. Stir well. Using a well-rounded tablespoon, form into balls about 1 inch across. Place them on an oiled baking sheet or, preferably, a baking sheet covered with a silicone mat or parchment paper. Bake for 20 minutes. Carefully turn over and bake fore 20 minutes more, until lightly browned.

Step 4

How long you cook them will depend on your air fryer. Preheat it to 390F. Place the balls in a single layer in the hot basket or tray. Air fry for 8 minutes or until they are becoming crispy. Shake the basket lightly to loosen them and turn and air fry another 2-5 minutes or until lightly browned.
