Salad seasoning/dressing

Just wondered if anyone had reccomendations of a good salad seasoning, like the type you sprinkle on salad!! I swore I had one once that was sooo good but can't remember what it was, and so I bought Johnnys salad seasoning and its not that good at all.. so thought maybe there was a different kind! Without adding too many extra cals or sodium

ALSO Ive always been a ranch- only kind of person, but i Loooooove olive garden salad, and wondered if anyone knew how to make the dressing?? I like mostly all salad with just a tiny bit of it is good enough and would really really enjoy some right about now

Or any other ideas to spice up my salad!!

Thx!
