Here is a protein/energy ball recipe that is perfect for a mid morning or mid afternoon snack.  You can change the ingredients to fit your taste but here is an example:

3/4 c of Natural Peanut Butter (or almond, cashew, soy nut, coconut butter or PB2 mixed with water)
1/2 c thick old fashioned oats (or ground flax, oat bran, hemp seed, almond meal, wheat bran…)
1/2 c protein powder (choc. or vanilla, make sure it have 25g of protein/serving and less than 3g of carbs/serving)
2 tbsp honey (chopped up dried fruit is a great substitute, you would use closer to 1/3c of dried fruit)
4 tbsp unsweetened shredded coconut (chopped nuts or chocolate chips)

Mix the ingredients in  food processor or blender.  Roll into 12 balls and place in the freezer for 1hr to harden.  You can keep them in the fridge for up to 1 week.  Also, you can choose to mix the coconut in with all the ingredients or use it as a topping to roll the balls in.  Below are the nutrition facts:
