There are a lot of healthy dressing you can buy, but I prefer the home-made since dressing is very easy to make
I'm not strictly following any diet but the simple idea is to avoid sugar if you want the dressing to be healthy. There is a recipe round up post I saved some months ago, maybe you'll find your best recipe here:

My favorite is red and white balsamic:
1 1/2 Cup Extra Virgin Olive Oil
1/4 Cup Red Balsamic Vinegar
1/4 Cup White Balsamic Vinegar
1 Teaspoon Stone Ground or Dijon Mustard – or to taste
2 Garlic Cloves – minced
1 Teaspoon Sea Salt – or to taste
Dash of Black Pepper
