1 box chopped frozen spinach (defrosted and water squeezed out)
salt & Pepper

Grease a square pan for thick bread or a rectangle pan for thinner bread. I make mine in a rectangle pan for the thinner looking bread. Now, the trick is to really grease your pan well with butter, then with pam or it will not come out. bake at 400 for 15 minutes or until firm. Let cool and using a spatula go around the edges and start to pry it up. It will be a little hard at first but then it will get easier once you get the sides started. It will come out in one piece. I cut in half twice and make two sandwiches. I toast them on the stove and add provolone, ham, turkey and grill it like a grilled cheese. Serve with mayo and mustard and wow, you must try
