How to buy salad greens
Select lettuce for a versatile option.
If you're not sure what type of greens work best with the salad you're planning, lettuce is usually the best choice. Lettuce has a mild, often sweet taste that goes well with almost anything, and is available in a variety of shapes and sizes.
You can choose from loose leaf and head lettuces. Loose leaf varieties come in loose bunches, while head lettuce grows in a tighter ball.
