Heat the oven to 375°F and grease a 9x13 dish.
Brown the sausage with the diced bell pepper in a skillet over medium-high heat for 8 minutes; drain.
Spread the hash browns in the dish, then top with the sausage mixture, sliced green onions, and 1.5 cups cheddar.
Whisk the eggs, milk, mustard, 0.5 tsp salt, and pepper and pour evenly over everything; top with the remaining cheese.
Bake 40 to 45 minutes until the center is set and doesn't jiggle. Serve with fruit for an easy breakfast-for-dinner night.
