I found this dressing on EatingWell.com.

Cilantro-lime Vinaigrette:

Ingredients

1 cup packed cilantro
1/2 cup extra-virgin olive oil
1/4 cup lime juice
1/4 cup orange juice (Note: To make this SB friendly, I used 1/2 C orange segments, since I was making it in a mini-food processor)
1/2 teaspoon salt
1/2 teaspoon pepper
Pinch of minced garlic
Puree cilantro, olive oil, lime juice, orange juice, salt, pepper and garlic in a blender or food processor until smooth.

This works on the Orange Avocado salad, but is also a delicious topping for fish!
