What is the title to a movie that stared Omar Sharif & Sofia Loren?

I saw this movie in the early 70s and this movie was already old. It was in color. It starred Omar Sharif who played a prince and was traveling, he came upon a saucey peasant woman and asks her to make a certain number of biscuits, she makes them but eats one and the story goes from there. Later in the movie Sofia must participate in a dishwashing contest against other princesses that want to marry the prince. This was an Italian movie. It was done in english and Itialian. I want to know what the title is to the english version.
