For the White Sauce: 

1. In a small saucepan, heat the oil over medium heat. Add the garlic and cook for a few minutes, stirring frequently, until the garlic is softened and fragrant.
2. Remove the pan from the heat and stir in the fresh dill, the ranch dressing, and a little salt and pepper,
3. Taste, and add more seasonings, as needed.

For the Pizza:

1. Preheat the oven to 475°F and line a large baking sheet with parchment paper. If you have a pizza stone, put it in the oven while it preheats.
2. Roll the dough out on a floured surface to a thin, large circle roughly 14-inches in diameter. Transfer the dough to the baking sheet (if using a pizza stone, transfer the dough to a parchment-lined pizza peel).
3. Spread the white sauce evenly over the crust, leaving a border around the edges.
4. Top with the cheeses, pickles, bacon, and pinch of salt and pepper, and a sprinkling of red pepper flakes (optional).
5. Transfer the pizza to the oven and cook for 10-12 minutes (start checking it around 8 minutes) or until the crust is crisp and golden and the cheese is melted, bubbly, and golden in spots.
6. Remove from the oven and allow to cool slightly before slicing. Garnish with fresh dill just before serving. Enjoy while warm.
