I am definately a Ranch fan. I've had a hard time finding a replacement for 'normal' ranch dressing, but the following have helped to make my salads edible again(
My favorite: Health Valley Organic Ranch Dressing.
Annie's Homegrown Organic Cowgirl Ranch Dressing
O Organics Ranch Dressing
Simply Organic Ranch Dressing Mix (individual serving packets)
Organicville Ranch Dressing
Newmans Own All Natual Ranch Dressing
There are a few others I am forgetting, but I have tried all of those and enjoy them.
I also shop at a local discount grocery where I am able to purchase a lot of my organic food (except for fresh produce) at a more affordable price. Salad dressings from there are usually between $.75 to $1.49.
But I think a few of the above mentioned brands can be found in most grocery stores for around $4-5.
I have yet to study which ones are higher quality, and better for you.
But plan to soon. So much to learn!
Best of luck!
