Cooking collard greens is straightforward and satisfying. Here are the steps to prepare them:

1. Wash and Clean: Rinse the collard greens thoroughly under cold water to remove any dirt. Remove any tough stems, and chop the leaves into bite-sized pieces.

2. Heat Oil: In a large skillet or pot, heat the olive oil over medium heat.

3. Sauté Aromatics: Add the minced garlic and diced onion to the skillet. Sauté for about 3-4 minutes, or until they become translucent and fragrant.

4. Add Collard Greens: Fold in the chopped collard greens. Stir to coat them with the oil and garlic mixture.

5. Pour in Broth: Add the vegetable broth to the skillet, making sure it covers the greens. If you want extra flavor, add red pepper flakes to spice things up.

6. Simmer: Cover the skillet and let the greens simmer for about 30-40 minutes. Stir occasionally until they are tender.

7. Season: After cooking, taste and season with salt, pepper, and vinegar to balance the flavors.

8. Serve: Remove from heat and transfer to a serving bowl. Enjoy your delicious collard greens hot!
