Cooking collard greens involves simmering the leaves in liquid until they are tender. The cooking time will vary depending on the age and toughness of the greens, but as a general rule, they should be cooked for at least 30 minutes, and up to 2 hours for older, tougher greens.
Collard greens are a nutritious vegetable that is a good source of vitamins A, C, and K, as well as calcium and iron. They are also a good source of fiber, which can help to keep you feeling full and satisfied after eating.
