Hi Gordon!
I've also been looking for "healthy" snacks...
I haven't quite found any "exactly". Maybe it's because I like fried food too much!
One I've found that I can buy from stores that sell Indian groceries are a kind of roasted or fried peas (I'm not sure which). I think they're delicious! They're salty and spicy and crunchy...
They are vegetables, after all! (Though they can be a bit oily...)
Here's what a package of them can look like...

(from
here...)
The Japanese also do a version called "wasabi peas"... It's like dried peas smeared with wasabi, which is like a strong green mustard... I'm not a big fan, but I like the Indian non-wasabi variety.
Actually... come to think of it, I also love boiled peanuts. I just wish I knew where to buy 'em... I don't think you can get 'em in my town, that I've seen.
I hope you liked this post. Now if you know of any (other) "healthy" snacks, please let me know...
Cheers,
Dien
