Salad and toppings?

I read a response to a question on here that said eating grilled chicken in a salad was bad for you if you used dressing. Does anyone know if this is really true? I love a salad with grilled chicken. I've also read that for it to be really healthy you should not only have no dressing but no cheese, bacon bits, or croutons either. Can you add any taste to this crunchy green stuff? Plain lettuce & plain raw veggies are yucky in my opinion. I've recently started eating a lot of grilled chicken salad with light cheese, bacon bits, & croutons. Will I lose any weight like this or am I just defeating my purpose with the toppings? Another thing I've noticed is that this salad doesn't fill me up for long. After 2 hours have ped I'm ready to eat again so I opt for another salad. I've been eating atleast 3-4 small salads a day or more. Can anyone offer any advice. It seems as if I stay hungry throughout the day. I want to lose some weight. I'd think that salad would have to be better for me.
