Community wiki question. I'd like to compile an index of uses for stale bread. Here's a couple off the top of my head. Feel free to just go ahead and edit this list:  As an ingredient  Breadcrumbs, fresh or dried Breadcrumbs as coating or panade for Schnitzels, etc. Breadcrumbs as a filler in Rissoles, Fish Cakes, Meat Balls, Meatloaf, etc. Breadcrumbs as a thickener in soup, sauce or gravy Croutons Stuffing   Appetizers  Bruschetta Panzanella salad (with tomatoes, olive oil, onions)   Soups  Gazpacho French onion soup Spanish garlic soup Tuscan Tomato and Bread Soup   Breakfast  French toast aka Pain Perdu, Eggy Bread Fried bread   Entrées  Bread galette (soften with eggs, cook into a sort of omelette) Fondue Toast, toasted sandwich   Dessert  Bread and butter pudding Bread pudding Bread Sauce Brown Betty Brown Bread Ice Cream Summer Pudding Christmas Pudding and others such as Figgy Duff made with dried fruit and breadcrumbs then steamed in a cloth. Queen of Puddings and all the other similar ones made with bread crumbs, such as Manchester and Monmouth Pudding. Sophie Grigson's Tunisian Orange Cake Steamed Puddings such as Cabinet, Chancellor's, Chocolate, Marmalade, Raspberry, Syrup or Treacle Pudding   Miscellaneous  
Stuffing. Pretty much any stale bread product can be made into stuffing: I once made an old batch of cinnamon rolls into stuffing for pork chops. I made enough chops for 2 days of leftovers, and my guests wolfed the entire batch in one meal. No leftovers for me, AND I get asked about it to this very day.
