Love olives? You'll like this sandwich. May use pimento-stuffed green olives as a sub for the black olives. Sandwiches will freeze. To freeze: Before broiling, wrap tightly in foil and place in Zip-Lock bag.
Puffs up while baking to a light topping; with delicious layers of spinach, bacon, and sour cream. A weeknight dinner. From America's Favorite Casseroles with modifications.
Note: Time to prepare does not include thawing the spinach.
