Add the avocado and garlic cloves to your food processor. Process until smooth.
Mix in the vinegar, cilantro, cumin, lime juice. Process to combine.
While the machine is running, slowly pour in the olive oil, until the mixture is the right consistency you want for your dressing. If it is still too thick, you can also add in a little bit of water until you get it just right. Serve immediately or refrigerate.
Please note : It will thicken when you refrigerate it, so you will need to add more water or oil to get it so that you can pour it again.
