Pulse the oats and the coconut until coarsely ground. Add peanut butter, honey, chia seeds, salt, vanilla, and chocolate chips. Pulse again until well-mixed and the chocolate chips are cut into smaller pieces. Roll into balls. (If it's too dry, just add a little more honey / peanut butter and mix again - I usually just eyeball the amounts until it gets sticky enough). Freeze until solid. Store in freezer or refrigerator.
