Steps to Make It
- Preheat your oven to 350°F. The warmth of the oven will soon fill your kitchen with delightful aromas.
- In a large skillet over medium heat, cook the sausage until browned. Stir occasionally, and enjoy the sizzling sound as it cooks.
- Add the diced onion and bell pepper to the skillet. Cook until they’re soft and fragrant, about 5 minutes.
- In a large bowl, whisk together the eggs and milk until well blended. The mixture should be smooth and creamy.

- Bake in the preheated oven for 45 minutes. It’s done when the top is golden and the center is set.
- Let it cool for a few minutes before serving. This will help it hold together when you slice it.
