Instructions

  1. Preheat oven to 350°F.
  2. Thaw the spinach and squeeze out as much juice as you can. This will keep your casserole from being watery.

  4. Spoon into a greased (with cooking spray) 2 quart pyrex dish.
  5. Top with bread crumbs.
  6. Bake covered with aluminum foil 30 to 35 minutes.
