1. Heat a large skillet over medium-high heat. Add the olive oil and let it heat up for a minute.

2. Add the ground sausage to the skillet and cook until browned, breaking it up into small pieces as it cooks.

3. Once the sausage is browned, add the diced onion and minced garlic to the skillet. Cook for a few minutes until the onion is translucent.

4. Add the chopped kale to the skillet and stir everything together. Cover the skillet with a lid and let it cook for 5-7 minutes, or until the kale is wilted and tender.

5. Remove the lid and season the skillet with salt and pepper to taste.

6. Serve hot and enjoy!
