Let's see if we can make a list with reasonably healthy snacks. Reasonable means different things to different people, so this will be fun.
A kale snack. Grocery Outlet has it occasionally for $2.99. Check the nutrition label for ingredients and nutrition. Not bad at all. If you like kale you should like its taste.
If you are on blood thinners (Aspirin does not count), do not eat this. The high Vitamin K content will affect your clotting factor (INR) and you might bleed profusely if you cut yourself or if you have a stroke etc.
