Healthy dressing for pasta?

[skully]

I am extremely picky with food and HATE tomotaoe dressing.

I often eat Organic fettuccine or whole wheat pasta, but I know the dressing (home-made) I use is not best, usually 1tbs of white creamy thing I dont know its name in English, and 1tbs of cheese.

What are healthier dressing options for things like pasta? I like lemon, olive oil and stuff liek that, don't like too many thing mixed together :S

No what is it made of and is it thick kind of dressing or light?

What's the taste like?
