How can I make this receipe healthy?

[Cathya]

Hi;

I have a wonderful brocolli salad that is easy to make and I want to be sure it's healthy to eat....I suspect it's not....and wonder if there's anything I can do to revise it? I apologize as this is not an important topic but I keep reading about Omego 3's and 6's and other healthy foods but I am having trouble retraining myself. Anyway, I take lots of brocolli, one chopped red onion, sunflower seeds, raisins (I have been cutting them out because of the sugar but ???) and add Ranch dressing. I usually just buy the Ranch dressing but got to thinking so I looked up the receipe for ranch dressing and it is as follows:
1 clove garlic
2/3 pinch of kosher salt
3/4 c buttermilk (this sounds bad!)
2 to 3 tbsp fresh lime juice
1 tbsp minched fresh cilantro
1 tbsp snipped parsley or fresh chives
1/3 to 1/2 c mayo or sour cream (yikes)
All in all the ranch dressing sounds fattening and full of stuff I shouldn't eat. Any suggestions? Thanks,

Cathy
