Remove the core of ripe avocado and mash avocado. Grate the carrots and radishes, chop parsleys and mix them gently with mashed avocado.
Add lemon juice (half of a lemon) and salt - depends on your taste buds - then mix them all together one more.
BON APPETIT !
(Avocado contains vegetable oils in it so adding olive oil depends on your choice. You can also eat this salad without adding olive oil in it)
