If you haven't heard of Nakd bars, I seriously think you need to spend more time researching healthy snacks :)
In all seriousness though, apparently they're not a thing in the US, but they are similar to something called Larabars.
They are a big brand of snack bars, that are "containing 100% natural ingredients with no added sugars or syrups, wheat, dairy and gluten free". I think that counts as pretty good for you! They are not perfect, and I'm not advising you to eat them five times a day or anything like that, as they contain natural sugars from the dates. But more importantly they are absolutely delicious and very filling.
Nakd bars are not particularly expensive, but they can be made at home quickly and very cheaply, from store cupboard ingredients (I know that not everyone has dates in their kitchen, but if you don't - you should.) As well as this, cooking things at home is really fun, especially with friends or kids. This is also classic five minute food so "I don't have time for cooking" isn't a valid excuse.
I haven't listed this as a recipe (instead as a food blog post) because I don't take credit for anything here. I'm simply reading the packaging carefully and sharing my knowledge. This is the back of a chocolate orange flavoured Nakd Bar:
