I really love to eat pizza.  Pizza is referring to the Italian flatbread dish with cheese as well as tomato sauce.
I love pizza! My favorite is ham and pinapple.
There are many different variations of pizza with additional meats, vegetables, and condiments.  Some even don't have cheese.
I don't know if I would like a pizza without cheese though. I love cheese!
Most people do.  The tradition version is one of the most popular foods in the world.
