In a tall jar or mixing container, combine the egg, almond milk, minced garlic, apple cider vinegar, Dijon mustard, salt, and garlic powder.

Blend using an immersion blender until smooth and creamy.

While continuing to blend, slowly drizzle in the avocado oil. Adding it slowly is key—this helps the dressing emulsify and prevents it from breaking.

Once the mixture has thickened to a creamy consistency, add in the fresh dill and chives. Blend briefly until herbs are incorporated.
