WHO IS BOB AND WHY IS HE MY UNCLE?
In English there are many expressions and one of them is: "....and bob's your uncle". For Spanish people this is a very hard expression to work out logically!
Essentially, it is used to emphasise that a process is easy to complete. So, for example: "To make tortilla all you need to do is mix eggs with potatoes and bob's your uncle!"
Now, before all of you complain, I know that it is very difficult to make a good tortilla! IT WAS JUST AN EXAMPLE!! jajaja
Hope that helps!
