Popcorn is not too bad and provides some fiber. Adding lots of butter or salt defeats things though. Find spices you can add for flavor but not too unhealthy. Baked pretzels are not too bad. Of course, fruits and veggies can make for a good snack when prepared the way you enjoy them most. Again, be sparring with any additions! You can soak some veggies in vinegar, dice up fruit to make a smoothie at home. Create your own dried fruit and nut mixes!
