Context paragraphs:
Melba toast: Melba toast is a dry, crisp and thinly sliced toast, often served with soup and salad or topped with either melted cheese or pâté.  It is named after Dame Nellie Melba, the stage name of Australian opera singer Helen Porter Mitchell.  Its name is thought to date from 1897, when the singer was very ill and it became a staple of her diet.  The toast was created for her by chef and fan Auguste Escoffier, who also created the Peach Melba dessert for her.  The hotel proprietor César Ritz supposedly named it in a conversation with Escoffier.

Cinnamon Toast Crunch: Cinnamon Toast Crunch (Known as Croque-Cannelle in French Canada, Curiously Cinnamon in the UK (previously Cinnamon Grahams), and as a different-tasting but similar-looking variant called Cini Minis in other European countries where available), is a brand cereal produced by General Mills and Nestlé.  The cereal was first produced in 1984.  Cinnamon Toast Crunch aims to provide the taste of cinnamon toast in a crunch cereal format.  The cereal consists of small squares or rectangles of wheat and rice covered with cinnamon and sugar.  Because of its rice content, when immersed in milk, one can hear "snap" sounds coming from it, similar to Rice Krispies.  In most European countries the product is sold in boxes but in Poland and Russia the cereal is sold in bags.  The product was originally marketed outside Europe with the mascot of a jolly baker named Chef Wendell, but was replaced with sentient Cinnamon Toast Crunch squares as mascots, who would often eat each other in commercials.

Toast (honor): A toast is a ritual in which a drink is taken as an expression of honor or goodwill.
