Preheat oven to 400.

Cook and crumble sausage in a skillet.

In a small bowl, beat the eggs, add milk, salt, and pepper.

Grease a 9x13" casserole dish. Layer hashbrowns, sausage, cheese, egg mixture. Top with green onions.

Bake for 45 minutes to 1 hour, until eggs are cooked through.

**timing can really vary depending on your oven temp!
