1 small onion, finely chopped
1/4 teaspoon pepper

Stir together first 6 ingredients (plus the meat and veggies, if using) in a large bowl.
Spoon potato mixture into a lightly greased 13- x 9-inch baking dish. Sprinkle evenly with crushed cornflakes, and drizzle evenly with butter. Bake immediately, or cover & refrigerate overnight and bake in the morning.
Bake at 325 degrees for 1 hour and 20 minutes or until bubbly.
