Preheat the oven to 350°F and line a baking sheet with foil.
Tear off eight pieces of foil and roll each piece into a wide cone with a hollow center (these will form the carrot molds). Set the cones upright on the prepared baking sheet.
Unwrap the 8-ounce package of crescent roll dough and press the perforated seams together to form one smooth sheet.
Using a knife or pizza cutter, cut the sealed dough sheet into 8 even lengthwise strips.
Starting at the pointed end of a foil cone, wrap one dough strip around the cone, overlapping slightly as you work upward. Place the wrapped cone seam-side down on the baking sheet. Repeat with the remaining cones and dough strips, leaving space between each.
Bake for 8–10 minutes, or until the dough is golden brown. Remove from the oven and let the shells cool until they are cool enough to handle.
Carefully remove the foil cones from the baked shells, fill each shell with chicken salad (or your chosen filling), and top each filled cone with a sprig of parsley to complete the carrot.
