Combine all ingredients in a blender and blend well till smooth. This will make about 2 ¼ cups and will keep up to 1 month. You need only 1 cup for the recipe.
Salad
Cook pasta according to directions. Drain and add dressing; tossing well to combine. Let cool.
Meanwhile cook bacon according to your taste. I like it just before it’s crispy! Cut into bite size pieces.
Add bacon, tomatoes, herbs, arugula and onion to the pasta and toss. Add more vinaigrette at this point if desired.
