Par-bake the pizza crust: unroll the pizza dough onto a baking sheet (previously greased with cooking spray) and spread it using your hands until it covers the whole sheet. Poke it all over with a fork and par-bake it for 7 mins in a 425 F oven.
Scramble the eggs: in a large bowl, whisk together the eggs, milk, minced onion, dry parsley, salt, and pepper. Melt the butter in a large skillet over medium heat, and scramble the eggs until light and fluffy.
Assemble the pizza:
spread the country sausage gravy over the par-baked pizza crust
spoon the scrambled eggs evenly over the gravy
sprinkle the bacon bits and shredded cheddar evenly over the eggs
Bake the pizza for 8-10 minutes until the edges are golden brown and the cheese has melted.
