Collard Greens vs Swiss Chard

When navigating the diverse world of leafy greens, you might find yourself comparing collard greens and Swiss chard – two nutritious options that grace many a kitchen with their vibrant presence. You’ll notice that, while both greens are leafy and can have a similar appearance, they are quite distinct in several ways.
