How to Make It
Preheat oven to 450°F. Coat a 15 1/2- x 10 1/2-inch jelly roll pan with oil. Arrange potatoes in a single layer in pan. Bake in preheated oven 10 minutes. Using the back of a wooden spoon, flatten potatoes until rounds touch and cover entire pan. Bake until crisp, about 20 minutes.
While potato crust bakes, cook eggs in a nonstick skillet over medium-low, stirring often, until very soft scrambled. Set aside.
Top crust evenly with 3/4 cup of the cheese. Top with scrambled eggs and bacon. Sprinkle remaining cheese over breakfast pizza. Bake at 450°F until cheese is melted and bubbly, 8 to 10 minutes. Garnish with chives.
