Pre-heat the oven to 375 degrees
In a skillet, cook the sausage and drain any extra fat
Over medium heat, stir in the cream cheese and then add the Rotel followed by the spinach. Mix until well combined and set aside to cool
In a bowl, beat the eggs and add a pinch of salt and pepper. Pour the egg mixture over the sausage mixture and top with the shredded cheese
Bake in the oven for 15 to 18 minutes or until the eggs are set and the cheese is melted. Broil the casserole for 2 - 3 minutes to achieve the perfect golden cheese look. Let cool for a few minutes and serve!
