Preheat the oven to 350°F (175°C).

In a skillet, cook the sausage over medium heat until browned.

In a mixing bowl, whisk together the eggs and milk.

Add the bread cubes and cooked sausage to the egg mixture, then stir in the cheese.

Pour the mixture into a greased baking dish.

Bake for 30-35 minutes or until the casserole is set and golden on top.
