We try to eat a salad daily. We add different ingredients to it to add different tastes such as, raisins, walnuts, pomegranates, avocados, cheese (I love sprinkling Parmesan over the salad), tuna, salmon, anchovies, etc. Anything goes! Make sure you use a healthy low fat dressing.
Here is one of our daily salads with chunks of leftover turkey in it.
Another way to make sure you get your greens is by drinking them. We especially like Genuine Health Greens+. It gives us energy as well as ensuring we're getting our daily "greens" nutrition.
