So far, the only long ride on which I have eaten these was in a car (but it was four days long, so it required its own kind of stamina). However, I imagine that they would be very effective for Bento boxing (as in brown bagging, not fighting Bentos). In addition, this recipe is simple enough that even the most recipe challenged (I'm looking at you, Speedy) should be able to make them. If you try the recipe and fail miserably, please share your experience in the comments so that I may make fun of you.
4 cups rolled oats
1 cup honey
1 cup sunflower seeds
1 cup chocolate chips
2/3 cup powdered milk
2-3 tbsp butter, softened
2 cups peanut butter (warmed for ease of mixing)
Heat oven to 350 degrees. Dump ingredients together and mix with hands. Roll into balls (size is up to you; mine are about a tablespoon, but I have a friend who makes them big enough to be a quarter cup). Bake for 5-6 minutes.
See how ridiculously simple that is? Also? Those ingredients are totally up for replacement. Try them with almond butter. Try them with nuts and dried fruit instead of chocolate chips. Mix another grain in there. Add some protein powder. The possibilities are practically endless.
By the way, if you're expecting pictures to come with these recipe posts, dream on. If I make anything good enough to share, there's no way there's ever going to be enough left over for a picture. Maybe I'll start taking pictures of empty, slightly-dirty plates. "See? This is where this delicious food used to be!"
