Place oats, tahini, honey, protein powder and chocolate chips in a large bowl and stir to combine.
Getting the mixture to combine takes a little arm muscle and it may seem too thick at first, but it will come together as you keep mixing. I used my hands to knead the dough near the end and that seems to help.
Once combined, use a small cookie scoop to scoop and form the dough into balls.
Store in a covered container in the fridge or freezer.
