My mom never bought Velveeta when I was a kid, so I didn't grow up with the 'love', and so therefore there's no nostalgia attached.
Velveeta, Dairylea, whatever... I don't like processed cheese. I make sandwiches, nachos, queso dip... anything cheesey, with real cheese... Double Gloucester or Red Leicester, usually.
Never had Rotel or tinned green chillies before, either. I know SO many Americans use this stuff, but if you didn't grow up with it, you don't miss it, so you probably don't need it.
