2Evenly divide dough into two pieces. Use flour on board. Stretch to fit.
3Fill a large bowl with cold water. Using a mandolin (or very sharp knife) slice potatoes paper-thin. I used a sharp knife and my arm still aches!
Put potatoes in water. Swirl to remove excess starch & prevent potatoes from turning brown. Drain & pat dry with paper towels. Place back in bowl
4Add garlic, onion, & crumbled bacon to potatoes in bowl. If you used yellow onion soaked in water, drain well.
5Season with salt and pepper. Drizzle a little olive oil over. Mix well
6Mix and add mozzarella & cheddar cheeses, dividing evenly between pizzas
7Top with salt, pepper, and the Parmesan.
8Bake pizzas in oven for 8-10 min. Crust should be golden brown, potato edges a little curled, and cheese is bubbly.
9To serve, top with a dollop of sour cream, diced tomatoes, basil, chopped chives, to taste.
