They're just slices of rye and pumpernickel cocktail bread, cut into triangles and toasted up. If you'd rather only buy one type of bread, just choose your favorite and use the whole loaf!

I love that heavy, black pumpernickel bread that you can buy ... The key to its flavour is the grain it’s made from — rye. Rye is closely related to wheat and barley, it contains gluten ...
