Lettuce
The most commonly consumed leafy green vegetable next to iceberg lettuce is the head lettuce, also known as butterhead lettuce. It has a pleasantly mild to slightly bitter taste and contains essential minerals and vitamins. Its leaves are soft, large-lobed, finely veined, and can have either smooth edges or fine serrations. Nutritionally, head lettuce stands out due to its high content of secondary plant compounds, which are predominantly found in the outer leaves.
