Healthy, low cost, no work snack food...any ideas?

So every night before I go to bed I end up finding myself eating a bowl of cereal, munching on a bunch of chips, eating a couple packs of fruit snacks. Not only do I feel terrible eating it because of the un-healthiness of it, but it also gets very expensive.

My question to everyone is, do you know of a healthy and cheap snack that is good to eat whenever, also before going to bed?

Also, my body responds to food based off of their texture rather than taste, so don't worry about it not tasting good.
