is the side salad at any resturants r u good for u when ur on a diet?

Answer 1

yes.
Just stay away from the regular dressings and any bacon/ham/pork you can add on there.
Drink some extra water while you're at it.

Answer 2

salads do not provide sufficient calories unless there is some form of protein added to it. most vegetables are very low calorie as the contain no fats and trace amounts of carbs.
