1 cup rolled oats
1/2 c semi-sweet chocolate chips (minis work great!)
1/2 c ground flax seed
1/2 c peanut butter
1/3 c honey
1 tsp vanilla extract
Mix well and put in the fridge for about 30 minutes. Take out and roll into small bite sized balls. Store in an airtight container in the fridge or freezer.
Can substitute with chopped nuts, chia seeds, different "butters" (almond, cashew), etc.
