Wilted kale, hot Italian sausage, and golden raisins make a balanced, hearty mixture.
Heat 1 tablespoon oil in a large skillet over medium heat. Cook sausage, breaking up large pieces with the back of a spoon, until browned, about 8 minutes. Transfer sausage to a bowl.
Add garlic to skillet. Cook until soft, about 1 minute. Add kale and water. Cook until kale wilts and is almost completely cooked, about 3 minutes. Drain on paper towels, squeezing out excess water.
Add kale mixture, raisins, pine nuts, sage, and remaining 2 tablespoons oil to bowl with sausage. Season with salt and pepper. Transfer to a cutting board, and finely chop. Transfer to a bowl, and refrigerate until ready to use.
Kale and Sausage Stuffing can be refrigerated for up to 3 hours.
