When I eat out and order a salad, the salad dressing is usually placed on the side of the plate or bowl.
In the past I would pour the whole container of dressing over the salad, then ask for another one.
Now what I do is keep it to the side and dip the veggies from the salad, just the tip, into the dressing and eat the salad that way.
It cuts down on calories and fat. I eat slower and enjoy each veggie in the salad more.
