Oh my gosh - I used to LOVE American cheese! When I was pregnant with my first, I ate American cheese sandwiches
every single day (and soft-serve chocolate frozen yogurt with sprinkles, but I digress...).
Kraft American cheese - not the individually wrapped ones, but the ones that came in the big block - solid 1 ounce slices, yes indeed. And while I usually ate them with wheat bread, what I really craved was white bread, and a generous serving of Miracle Whip and crunchy ice berg lettuce. Near the end of my pregnancy, when I was getting up to go pee in the middle of the night, I would make myself a half an American cheese sandwich before I went back to bed.
And while I was never a fan of Velveeta by itself, it makes a killer cheese dip with a can of Rotel stirred in and all heated up.
And yeah, I can see why people say the Chao reminds them of American - it's so very mild. It probably reminds me more of Monterey Jack.
