I grew up on Velveeta! We had Velveeta grilled cheese sandwiches, Velveeta in 'homemade' macaroni and cheese (not the kind with the powder from a box), a little Velveeta chucked into spaghetti with meat sauce/meat balls, Velveeta on what we called 'scalloped' potatoes, Velveeta cheese sauce for cauliflower or broccoli, Velveeta in all sorts of various casseroles - pork chops/potatoes/onions/Velveeta, turkey casserole after Thanksgiving with all sorts of stuff in it including a bit of Velveeta. It was Velveeta all around! Our refrigerator was never without an opened block of Velveeta in it, and one in the pantry waiting as well.

I usually bring a bit of Velveeta back from the US when I go, but it's enough to keep me happy for another year or so. It tastes nasty to eat on its own, but it's magic when melted & combined with Rotel for dipping tortilla chips.

Conversely, we were not allowed sugared cereals and not much Kool Aid as I recall. We did get soda pop though.
PS - You can also freeze Velveeta & it's really neat after it's been frozen because you can see all the salt crystals show up in the yellow stuff. I think it has a super-duper high salt content - so it's best that I only have it
very infrequently. I also think that, now, it includes high fructose corn syrup - which I think is a new development from the Velveeta while I was growing up, but I could be wrong.
