With the processor running, add lemon juice, tahini, garlic, and salt. Blend until smooth, about 5 minutes. You can also add 2 ice cubes for extra creamy consistency.
Add avocados and cilantro to the processor. Continue to blend until the mixture is smooth and creamy. Adjust flavor with additional lemon juice or salt if needed.
Transfer the hummus to a serving dish, drizzle with olive oil, and garnish with additional cilantro. Serve immediately or chill to enhance the flavors.
