Grease a 15 × 11 × 2.75 inch baking pan and set aside. In a large bowl, whisk together the eggs and milk, then season with salt and pepper to taste. Crumble the Bridgford Cheesy Jalapeño Biscuits into an even layer across the bottom of the prepared pan. Sprinkle the diced cooked sausage and shredded sharp Cheddar cheese evenly over the biscuits. Pour the egg mixture over the top, cover the pan with foil, and refrigerate overnight. When ready to bake, remove the casserole from the refrigerator and preheat the oven to 350 degrees. Bake for approximately 40 minutes, or until the casserole is cooked through and lightly browned around the edges.
