I found pre-packaged meals called Picnic to Go while browsing though my local Target. There are some with nut butters and crackers and others with hard salami and pepperoni. They come in a box but each part of the meal is packaged separately so they can be taken out of the box and take up a little less room in your pack. I haven't actually taken them out with me yet but they are a part of my meal plan for my upcoming trip.
