Salads provide many health benefits. There are four main types - appetizer, accompaniment, main dish, and dessert. They contain nutrients like vitamins, minerals, fiber, protein and carbohydrates. When making a salad, it's important to use fresh, high-quality ingredients and toss them gently to avoid bruising. Common salad greens include iceberg, butterhead, romaine, leaf and other options like endive, cabbage and watercress. Proper storage and handling of greens helps keep them crisp.
