Add a second story to your salad construction with some healthy fats. Combined with protein and carbohydrate, a small amount of healthy fat will turn your salad into a satisfying meal that won't leave you hungry. 

Avoid full-fat and cream-based dressings and mayo-based potato/macaroni salads, which are essentially unhealthy fat. Instead look for sunflower seeds and nuts, such as almonds and walnuts. These contribute to a satisfying meal and are excellent sources of monounsaturated fats, as well as protein, fiber and vitamins.

If your salad bar offers it, a serving size of about half an avocado is another rich source of healthy fat. And if you want to add a small amount of cheese for flavor, make sure you opt for grated favorites like Parmesan or Romano, where a little goes a long way on taste.

By now you've put together a salad that should entice any appetite - but of course at the end of the bar come those corrupting crunchies and dressings-to-kill. Don't let a heavy roof do in a healthy, calorie-controlled salad!

When it comes to salad dressings and other add-ons, follow these fundamental salad-roofing codes:

• Choose low and non-fat dressings only
• Choose fat-free croutons or none
• Choose soy bacon, not real bacon
• Avoid the following roof-cavers:

Now you're ready to put on your hard hat and start building a salad masterpiece - enjoy!
