Preheat the oven to 400°F(200C). Line a large baking sheet with parchment paper.
Roll out the pizza dough onto the parchment paper.
Bake for 12-15 minutes, until golden and puffy, then remove from the oven and let cool completely.
Transfer the cooled crust to a large cutting board.
While the crust is baking, mix together the cream cheese, sour cream, chives, dill, and Ranch seasoning mix. Set aside until needed.
Once you’re ready to dress the pizza, spread the cheese mixture onto the crust evenly. Arrange the broccoli, carrots, bell peppers, and onions on the pizza. Serve while fresh.
