Salad greens should be washed and dried before using. A salad spinner greatly simplifies this process. It has been said that the familiar, mild tasting iceberg lettuce has limited nutritional value. Although other salad greens contain more nutrients, iceberg lettuce does provide a fair amount of folate. Most types of lettuce contain some folate, vitamins A and C, potassium and fibre.
Salad greens are low in calories, but the calories add up quickly if drowned in a high-fat dressing.
Other alternatives include herb vinegar mixed with a little olive oil, a sprinkling of lemon juice and herbs or low-fat yogurt combined with finely chopped parsley, garlic and lemon juice.
