Salt and vinegar, but not too vinegary. some of them are.
For basic, plain Utz. I remember, back in the 80's Food and Wine magazine, which my dad got, named Utz the best chips in the US. and at the time you could only get them in the general area of PA where they were made. thankfully, now they're available here in NJ!
I like trying other fancy flavors. Just bought some cheddar horseradish from Trader Joes. while they are a bit spicy, they are delicious! i ate a farily large bag in 2 days.
