Preheat your oven to 350 degrees and spray a 9 by 13 inch baking dish with cooking spray.
Cook the Horizon Mac N Cheese according to package instructions.
While the Mac N Cheese is cooking, over medium heat cook the breakfast sausage until the sausage is cooked through. Remove from the pan and let drain on paper towel.
Spray the pan with cooking spray and cook the pepper, onion, and garlic until the onion is transparent and the peppers are fork tender. About five minutes. Remove from the pan and set aside.
Combine the whisked eggs, cream, and dash of salt and pepper. Scramble until the eggs are fully cooked.
Combine all the cooked ingredients with the Mac N Cheese and add to the baking dish. Top with the mozzarella cheese and bake for 20 minutes. Serve while hot.
