Breakfast Pizza (with crescent roll crust)

2 cans crescent rolls (8oz each)
1 pound breakfast sausage
2 cups cheddar cheese
3 cups frozen hash browns or tater tots
8 eggs
1/4 cup milk
3 teaspoons mustard

Arrange crescent rolls on a greased cookie sheet to make crust; flatten and press edges up a little. In a mixing bowl, mix eggs, milk, and mustard (and salt and pepper to taste). Top crust with crumbled sausage (cooked and drained), potatoes, cheese, and egg mixture. Bake at 375 until crust is brown and eggs are set (approx 25 minutes).
