"101 Cozy Casseroles" ($14.95) that goes together in minutes and tastes as good as the sandwich that it's based on. You can alter it to your tastes, using pastrami instead of corned beef; just make sure you follow a few of the directions. When I tested the recipe, I cut the bread into strips, not cubes and I found myself having to cut the casserole with a knife; not hard, but not exactly ideal, either. I've never known Thousand Island to be so liquid that you could drizzle it, so I slathered it on top and then spread it out. I also didn't stick too closely to the ingredients, but used more cheese, corned beef and dressing, until it covered the whole dish. Reuben Casserole 6 slices rye bread, cubed 1 (16-ounce) sauerkraut, drained and rinsed 1 pound sliced deli corned beef, cut into strips 3/4 cup Thousand island salad dressing 2 cups shredded Swiss cheese Preheat oven to 400 degrees. Arrange bread cubes in a greased 9-by-13-inch baking pan. Cover with sauerkraut. Layer corned beef over sauerkraut. Drizzle salad dressing over top. Cover with aluminum foil and bake for 20 minutes. Remove foil; sprinkle with cheese and bake, uncovered for another 10 minutes or until cheese is melted and bubbly. Makes 6 servings. From "101 Cozy Casseroles"
