Velveeta.
Velveeta has been a part of American diets since 1928. Known for it's meltability, my family has used it as long as I can remember.
I am very much against food snobbery. This was probably because I was born right after the depression and was a little girl during the second world war when food was rationed.
I also was expected to eat what was put in front of me and like most girl teens of that era I was given cooking and sewing classes in school. My sewing skills aren't too hot, but I am a halfway decent cook and I still use Velveeta.
