Farmer's Breakfast Casserole

So easy, and so so good!  I'm not a big fan of eggs, so I usually don't like breakfast casseroles.  The original recipe (The Big Book of Breakfasts) calls for cubed ham, but I LOVE sausage. 

Farmer's Breakfast Casserole

3 c. frozen cubed hash brown potatoes, slightly thawed
1/2 c. grated pepper Jack cheese
1/3 c. grated Cheddar or Monterey Jack cheese
1 lb. sausage, browned and drained
6 to 8 green onions, sliced
4 large eggs
1 1/2 c. milk
Salt
Pepper

Preheat oven to 350 degrees.  In an 8x8 lightly sprayed dish, arrange a layer of hash browns, grated cheese, sausage, and green onions. 
In a medium bowl, whisk together eggs, milk, salt and pepper.  Pour egg mixture over potato mixture.  Bake uncovered until center is set, about 50 minutes.  Let stand for 10 minutes.
