Start by removing the crescent dough from its packaging—don't unroll it just yet! Cut each tube into 8 even slices, creating a total of 16 pieces. Preheat your oven to 375°F (190°C) while you work. With a 14-inch pizza pan in hand, arrange those slices in a circle, overlapping slightly to create a wreath shape. Leave the center open, and imagine how delightful it’ll look once it’s baked!

Time to bring a little heat! Place your prepared pizza pan in the preheated oven and bake for about 15 to 20 minutes. You'll know it’s ready when it turns a lovely golden brown. Once baked, remove the pan from the oven and allow it to cool for about 5 minutes. Carefully transfer your crescent roll wreath to a serving platter and let it cool completely.

Now, let's work on that delicious filling! In a medium mixing bowl, combine the softened cream cheese and sour cream. Using a hand mixer, beat them until the mixture is smooth and creamy. Add in the dried dill and onion powder, mixing until well combined.

Spread that creamy goodness evenly across the cooled crescent dough wreath. Now for the fun part—top your spread with the chopped broccoli, sweet red pepper, chopped celery, and black olives, if using. Don’t be shy; pile it up! Finally, finish with fresh celery leaves for that touch of green.
