Combine blueberries, pecans, cacao nibs, almond butter, chia seeds, maple syrup and salt in a food processor. Pulse until finely chopped, 10 to 20 times, then process for about 1 minute, scraping down the sides as necessary, until the mixture is crumbly but can be pressed to form a cohesive ball.
With wet hands (to prevent the mixture from sticking to them), squeeze about 1 tablespoon of the mixture tightly between your hands and roll into a ball. Place in a storage container. Repeat with the remaining mixture.
