Cut the avocados in half, remove the pit, and scoop the flesh into a blender or food processor.
Peel the cucumber, chop it into chunks, and add it to the blender.
Pour in the vegetable broth, and then add the Greek yogurt, lime juice, olive oil, minced garlic, and a pinch of salt.
Blend the mixture until it is super creamy and smooth. If the consistency is too thick, you can add more vegetable broth until you reach your desired texture.
Taste the soup and adjust the seasoning with more salt or lime juice if necessary.
Once blended, transfer the soup into a mixing bowl or directly into serving bowls.
Chill the soup in the refrigerator for at least 30 minutes to enhance the flavors.
Before serving, stir the soup again and then garnish with fresh herbs on top.
