And fruits, I hope? :-)

Also, you mention carrots, but there's lots of other vegetables that taste nicely when eaten raw that require little to no preparation time. I recognize that this is not mainstream at all but lately I've begun eating all kinds of vegetables as a snack. Eg iceberg salad: if you take the outer 5 or so leaves off, then the rest has not usually been touched by pesticides, so you can just eat that without all the washing cutting prep etc. I've found that just putting an iceberg salad next to my keyboard works exactly the same as just putting a bag of crisps there: when i look up an hour later, it's all gone.

Similar tricks: pointed red peppers only need washing, and then you can eat them as if they're a mars bar. The seeds are only at the very end. bags of pre-cut lettuce. Also, way too few people are aware that cauliflower tastes great raw. It's a bit of work to clean (but not too bad) but cauliflowers tend to be huge so you can cut one into pieces, put the pieces into four bags and bring a bag every next day or so. It also stays good super long.

I also like cabbage (you can also remove the outer leaves and eat the rest without washing), but it has a pretty strong taste and I recognize that this might not be for everyone :-)
