Creating the Crescent Roll Breakfast Casserole is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Baking Dish: Lightly grease a 9×13-inch baking dish with cooking spray or butter.
3. Unroll Crescent Rolls: Open the cans of crescent rolls and unroll them. Lay the dough flat in the baking dish, pressing together the seams to form a crust.
4. Cook the Sausage: In a skillet over medium heat, cook the crumbled breakfast sausage until browned. Drain any excess fat and set aside.
5. Mix Eggs and Milk: In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until well combined.
6. Add Fillings: Stir in the cooked sausage, diced bell peppers, onions, and shredded cheese into the egg mixture.
7. Pour Mixture: Pour the egg mixture evenly over the crescent roll crust in the baking dish.
8. Bake: Bake in the preheated oven for 25-30 minutes, or until the eggs are set and the top is golden brown.
9. Cool Slightly: Remove from the oven and let it cool for a few minutes before slicing.
10. Garnish: If desired, sprinkle fresh herbs over the top for added flavor and presentation.
