and they have to taste somewhat good. i tried a recipe off of here that absolutely sucked one time. it tasted like super dry and salty peanut butter and required atleast 1 gallon of water to eat one bar, just to wash the damn thing down.
apple sauce
oatmeal powder (put it in a blender until it becomes like flower
protein powder of choice
splenda
eggs
mix it up and bake it at 350 for 12 mins
