- 1 pound bulk pork sausage

- 2 cups milk
- 1 teaspoon salt
- 1 teaspoon ground mustard
- 1 cup shredded Cheddar cheese
- 2 (8 ounce) packages refrigerated crescent rolls
- Heat a large skillet over medium-high heat and stir in sausage. Cook and stir until sausage is crumbly, evenly browned, and no longer pink, 5 to 7 minutes. Drain and discard any excess grease.

- Roll out crescent roll dough and place one sheet on the bottom of a large baking dish.

- Preheat oven to 350 degrees F (175 degrees C).
- Bake in the preheated oven until egg is set and a knife inserted near the center comes out clean, about 40 minutes.
