Spread dough from crescent roll mix onto a baking sheet - try to form a large square - bake to well done (according to pkg. directions).
Mix softened cream cheese, mayo and dressing packet together (I like to let it sit overnight in the fridge).
Once crescent roll has completely cooled, spread mixture as evenly as possible over crescent roll square. Sprinkle onions first, followed by tomatoes and broccoli and black olives. Cut into small 2 inch squares and enjoy.
