Flavors will be different depending on the type of oil and vinegar you use. Consider this a blank canvas and feel free to add whatever flavors you like. Honey, herbs, fruit, spices - whatever you want. There's no wrong vinaigrette if you like it.

This is a basic vinaigrette.

1. In a blender add the onion, garlic and vinegar and puree until smooth
2. While blender is running slowly drizzle in the oil
3. Season with salt and pepper
