Roughly chop the chickpeas and place in a bowl. Add the minced herbs and scallions to the chickpeas and give a quick toss.
In a separate bowl, whisk together mayo and lemon juice.
Cut the avocado in half, remove the pit, and cut each half into ¼” cubes. Place in the bowl and pour the mayo mixture over the chickpeas and avocado. Toss until well combine.
Taste and add salt and pepper to your preferred taste.
