Preheat oven to 400 degrees. Grease 9x13" baking dish with cooking spray. Set aside.

In a medium skillet over medium heat cook the sausage, breaking it up as it cooks, letting it brown completely.

Unroll the crescent rolls and spread them out in the bottom of a 9x13" pan, pressing the seams together to make one large sheet of dough.

Sprinkle the sausage over the dough.

Sprinkle the cheese on top of the sausage.

In a medium bowl, whisk the eggs with the milk, rosemary, salt, and pepper. Pour the egg mixture over the top of the casserole.

Bake at 400 degrees for 20-25 minutes, or until the crust is golden and the eggs are set.

Let cool 5 minutes, then cut into slices. Enjoy!
