Preheat oven to 375°F and line a large round pizza pan or baking sheet with parchment.
Arrange crescent triangles in a circle with points out and bases overlapping in the center, forming a ring.
Mix cream cheese with ranch seasoning, broccoli, red pepper, and cheddar.
Spoon filling evenly over the base ring of the dough.
Fold each point over the filling and tuck under the base to form a wreath shape.
Brush with beaten egg and bake 20 to 24 minutes until golden.
Let cool slightly, then serve on the pan.
