Preheat the oven to 175°C (350°F) and thoroughly grease a 23 x 33 cm baking dish to prevent sticking.

Arrange the quartered biscuit pieces evenly across the bottom of the prepared baking dish and gently press down to form a solid foundation.

In a large skillet over medium heat, cook the pork breakfast sausage, breaking it into crumbles with a spatula, until browned and cooked through. Drain excess fat.

Distribute the cooked sausage evenly over the biscuit layer in the baking dish.

In a large bowl, vigorously whisk together the eggs, milk or cream, salt, black pepper, and garlic powder until completely blended.

Pour the egg mixture over the sausage and biscuits, ensuring full coverage. Evenly top with shredded mozzarella and cheddar cheese. Sprinkle diced green chilies on top if using.

Transfer the assembled casserole to the preheated oven. Bake for 30-35 minutes, until the eggs are fully set and the cheese is golden and bubbling. For even browning, tent with foil if the top browns too quickly.
