Not to me, as I eat ham, turkey, roast beef, mustard, tomato, lettuce and pickles on sandwiches and I don’t eat those things on pizza. I guess it depends on what you eat on a sandwich vs what toppings you eat on pizza!
Great question
Yes, I can see that! No matter how you look at it pizza is yummier than a sandwich any day lol

Well technically pizza is made from dough and so is bread. So, you could look at it like a one slice sandwich.
