In a blender blend the flax seed until it is a powder.

Add in oatmeal, M&M's, and peanut butter. Either switch the blade to stir or fold it in by hand. I prefer to use the mixer because it chops up the oats a bit to a texture that is better, but with M&M's you are going to want to hand stir them in.

Once fully mixed mold into balls and set on wax paper.

Let them harden for about 15 minutes and then eat!
