How to Make It
Stir together biscuit mix and 1/2 cup water until dough forms.
Turn dough out onto a lightly floured surface; knead 4 or 5 times. Pat into a 12-inch circle on a lightly greased baking sheet.
Cook sausage in a large skillet, stirring until it crumbles and is no longer pink; drain well.
Layer dough evenly with sausage, hash browns, and cheese. Whisk together eggs, milk, and pepper; pour mixture evenly over cheese.
Bake at 400° for 30 minutes or until golden.
