Preheat your oven to 350°F and grease a 9×13 baking dish.
Add the cubed King’s Hawaiian rolls into the baking dish.
In a skillet, cook the sausage until browned. Add the diced red pepper and cook until softened.
Stir in the cream cheese until fully melted and combined, then remove from heat.
In a large bowl, whisk together the eggs, milk, dry mustard, 1 cup cheddar cheese, green onions, salt, and pepper.
Pour the egg mixture evenly over the cubed rolls.
Spoon the sausage mixture on top and gently fold everything together so the rolls soak up the liquid.
Top with the remaining 1 cup cheddar cheese.
Bake for 35–40 minutes, or until the center is set and the top is golden brown.
Serve warm and enjoy your cozy holiday breakfast!
