PIZZA CRUST: Stretch pizza dough to fit a greased 1/2 sheet pan (18 x 13-inches). Press onto the bottom and up the sides of pan to form a crust. Brush with olive oil and bake for 8 minutes or until golden brown.
SAUSAGE GRAVY: Meanwhile, in a large skillet, crumble and cook sausage over medium heat until browned. Stir in flour until dissolved. Gradually add warm milk. Cook stirring gravy until thick and bubbly, adding more milk as necessary to control the thickness, season with salt and pepper.
HASHBROWNS: Heat 1 tablespoon butter and 2 tablespoons vegetable oil in a large non-stick skillet over medium-high heat. Add chopped onions and a half bag of frozen hash browns in an even layer; season with salt and pepper. Cook 5-7 minutes. Carefully turn hash browns. Cook for another 4-6 minutes until golden brown (Do not stir). Season hash browns with more salt and pepper if needed.
SCRAMBLED EGGS: In a small bowl, whisk together eggs. In a large skillet, heat 1 tablespoon butter over medium heat. Add eggs, cook and stir until almost set; remove from heat.
TO ASSEMBLE: Sprinkle 1 cup cheddar cheese over baked crust. Top with sausage gravy, hash browns and eggs. Sprinkle remaining 1 cup cheese over all. Bake pizza for 10 minutes or until cheese is melted. Turn heat up to broil for 2-3 minutes if desired. Cut into squares.
