Preheat oven to 350F. Line cookie sheet with parchment paper and set aside.

In a large bowl, combine flour, coconut, salt, sweetened condensed milk and vanilla, until dough forms. Drop by spoonful onto prepared cookie sheet. Use your thumb or a spoon to make an indentation in the center to form a nest shape. Bake for 12 - 15 minutes, until coconut starts to turn golden brown. Remove and let cool. 

When completely cooled, fill each nest with 1 - 2 tsp. of Nutella and top with a few chocolate eggs.
