Preheat your oven to 400 degrees. Grease a 9 inch baking dish with cooking spray.

Cook the sausage until browned in a large skillet with the onions and peppers. Stir in the hash browns and cheese. Spread into your prepared dish.

Whisk together the Bisquick, milk, eggs, salt and pepper. Pour over your sausage mixture. Bake for 45 minutes or until a knife comes out clean.
