Alternative to popcorn? Aka salty snacks

Hi all,

Sadly I have corn allergies so can't have popcorn but I am a big salty, crispy or chewy fan. Any ideas or tips on options for savory snacks that are low cal? Ideally something beyond cucumbers and carrots haha

ETA - so jealous of the US products, Im based in Sweden and over here its practically impossible to find diet options
