1 TB Olive Oil
1 Onion, sliced
2 Apples, cored and cut into bite-sized pieces
2 tsp Apple Cider Vinegar
1/8 tsp Sea Salt*
1/8 tsp Ground Black Pepper*
4 cups chopped Kale leaves
Heat olive oil in a large skillet over medium heat, cook and stir until onions are tender, about 4 minutes. Add apples, vinegar, salt and pepper. Cover skillet and cook until apples are tender, about 3 minutes. Add kale. Cover and cook until kale is tender, 4 to 5 minutes.
*I think this is probably not enough salt or pepper, so I would definitely taste and adjust.
