i ate chinese noodles with ketchup yesterday and it didn't taste very well. i do not advise you to try it at home unless you have a prescription from your local doctor like me (because i am allergic to milk, but sometimes i eat cereals with milk and my parents don't know and then my stomache hurts and it makes funny noises and my brain hurts :( )

with pasta it's different though, because pasta with no sauce has no taste, which means that you must add something to it. pizza is like pasta but you can't eat both pizza and noodles at the same time because of the bread

some people across the web do not like pizza and they tried eating their slices of toast with ketchup, but that is wrong.
