- 1 teaspoon granulated garlic or garlic powder

Directions:
- Preheat the oven to 375 degrees Fahrenheit.

- In a small bowl, whisk together the eggs and milk until fully combined.
- Layer the cooked sausage, onions, peppers, and bacon on top of the hash browns. Sprinkle 2 cups of cheese over this layer. Then, pour the egg mixture evenly over everything.
- Place the skillet in the oven on the middle rack and bake for 40-45 minutes, or until just set and not wobbly in the center.
- After 40-45 minutes, add the remaining cheese on top and return it to the oven for an additional 10-12 minutes.
- Once done, garnish with sliced green onions or chives before serving.
