In a large mixing bowl, combine the rolled oats, chocolate chips, protein powder, chia seeds, and salt. Stir until the dry ingredients are evenly mixed.

Add the peanut butter, honey, and vanilla extract to the bowl. Stir the mixture until all ingredients come together into a thick dough-like consistency.

Use a spoon or small scoop to portion the mixture and roll it between your hands to form small bite-sized balls.

Place the protein balls on a tray or plate and refrigerate for about 20–30 minutes to firm up before serving.
