Salads are a great addition for helping dieters, it keeps you full-feeling and you can add great nutrition to your diets.
Throw in some grape tomatoes, add fresh spinach (for the iron) and sprinkle craisins and nuts on it for texture and taste.
Most importantly, put your dressings in a ramekin on the side - dip your fork into it and take a bite. It really helps and you will notice how little dressing you really need on your salads!
Plain ice berg lettuce gets very boring, don't hesitate to change up what you use. There is no rule that says your salad needs to have somethings you don't like. Put vegetables that are fresh and that you eat in them!
