Preheat oven to 400 degrees F. Grease a square baking dish (8 x 8 inches or 9 x 9 inches) and set aside.

In a sauté pan over medium heat, add the sausage, onion, and bell pepper. Cook while breaking up the meat with a spatula until the sausage is cooked all the way through, about 7 to 8 minutes.

Transfer the meat mixture (including the fat) to the casserole dish and stir in the frozen hash browns and ¾ cup of the grated cheese.

In a medium sized mixing bowl, whisk together the flour, baking powder, salt, and pepper. Whisk in the milk and eggs until well combined but not overmixed. Pour over the sausage mixture in the casserole dish ensuring even coverage.

Bake uncovered until light brown on top and around the edges, about 35 to 40 minutes.

Sprinkle the remaining ½ cup cheese on top and bake for 2 more minutes.

Serve with fruit for breakfast or with a salad for lunch. Enjoy!
