Nutella and Vegemite share some similarities, such as their dark brown color and creamy texture; Nutella and Vegemite are actually quite different.  Nutella is made from a blend of hazelnuts, cocoa, and skim milk, while Vegemite is made from leftover brewer's yeast extract.  As a result, Nutella has a sweet, nutty flavor, while Vegemite is very salty with a slightly bitter taste.  In addition, Nutella is often spread on toast or used as a filling for crepes, while Vegemite is typically eaten with cheese on crackers or bread.  So while they may look alike, Nutella and Vegemite are actually two very different spreads.
