You can have as much salad as you want, as long as you control how much salad dressing you eat.
I really good salad dressing is diet Kraft Miracle whip with lemon juice. You can stretch that salad dressing a long way, which helps your calorie intake. Many body builders will use vinegar and lemon juice for dressing, because there is almost no calories in that.

Maybe try this. Sometimes I have two salads at the table. A more greasy and vinegary and delicious salad. Then in another bowl some plain cut up vegetables. Maybe a cut up apple. I eat from each as I go along.
Have as much as you want.
