After a long and careful study of what makes a good salad, I have decided upon three key components, in addition to your standard greens and veggies:
1. Something sweet (like dried cranberries, raisins, pomegranate seeds, chopped apples, etc.)
2. Something crunchy (like croutons, crushed pita chips, tortilla chips, nuts, etc.)
3. Cheese (depending on the salad, goat cheese, feta, and parmesan are all good choices)
Of course you must use these things in moderation to avoid overdoing it and adding too much fat/calories/etc to a dish that, essentially, is supposed to be a healthy addition to your meal.
