An otherwise healthy salad can become a diet disaster if it's loaded with fatty dressing. To avoid this pitfall, try this trick: Ask for your dressing on the side, and dip your fork into the dressing
before loading it up with a bite of salad. You'll still get the taste of salad dressing on every bite, but will consume only a fraction of what you are given.
Another sure-fire way to nutritionally ruin a salad is to add fatty, unhealthy toppings like bacon, cheese, croutons, and fried food. Load it up with fresh veggies, grilled toppings, and a lighter dressing, like olive oil and vinegar, instead.
