Zest one lime first, then juice both limes into a small bowl. Mince the garlic and roughly chop the cilantro, including some tender stems for extra flavor.

In a food processor or blender, combine the avocado flesh, lime juice, lime zest, Greek yogurt, olive oil, garlic, cilantro, honey, salt, and pepper. Process until completely smooth, stopping to scrape down the sides once, about 1 minute.

With the machine running, drizzle in the cold water through the feed tube. Blend until the dressing is pourable but still coats the back of a spoon, similar to heavy cream. Add more water 1 tablespoon at a time if needed.

Taste and adjust salt, lime, or honey as needed. The dressing will taste bright and slightly tangy. Let it sit for 5 minutes so the flavors meld, then taste again and adjust if necessary.

Use immediately or transfer to an airtight container. Press plastic wrap directly onto the surface to prevent browning, then seal. Refrigerate for up to 3 days. Stir before using as it will thicken when cold.
