Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 475 degrees. Wash and dry produce.

Sprinkle 3 TBSP flour over a clean work surface. Remove pizza dough from packaging and place on floured surface. Shape each piece of dough into a ball. (TIP: Spray your hands with nonstick cooking spray or dust with flour to prevent sticking.) Evenly sprinkle dough balls with 2 TBSP flour. Cover with a clean kitchen towel and let rest at room temperature for 20 minutes.

While dough rests, pat potato slices dry with paper towels; season with salt and pepper. Trim and thinly slice scallions on an angle.

Add bacon* to a large dry pan in a single layer; heat over medium-high heat. Cook, turning occasionally, until cooked but not fully crisped, 6-10 minutes.

Turn off heat; transfer bacon to a paper-towel-lined plate. Once cool enough to handle, roughly chop.

Once dough has rested 20 minutes, line a baking sheet (two baking sheets for 4 servings) with parchment paper. Carefully press and stretch each dough ball into a rough oval shape and place on one side of prepared sheet (you'll have two dough ovals per baking sheet). TIP: If needed, use a rolling pin to help roll out dough.

Cover dough with a clean kitchen towel and let rest 15 minutes. TIP: This will make stretching the dough into a larger shape even easier!

Once dough has rested 15 minutes, use floured hands to press and stretch dough on baking sheet into larger oval shapes, about 10 inches long and 5-6 inches wide.

Evenly spread dough with dressing. Arrange potato slices on top in an even layer. Evenly sprinkle with white cheddar and half the yellow cheddar (you'll use the rest later). Top with bacon.

Drizzle or brush edges of dough with olive oil.

Bake pizzas on top rack until crusts are golden brown and crisp, 14-18 minutes. (For 4 servings, bake on top and middle racks, swapping rack positions halfway through.)

When pizzas are done, immediately sprinkle with remaining yellow cheddar; let rest for a few minutes.

Snip one corner of sour cream packets and drizzle over pizzas; sprinkle with scallions. Crush potato chips in their package and sprinkle over pizzas.

Slice pizzas as desired and serve.
